Chlamydia ig. Deciphering the analysis for chlamydia in the blood

Let's first understand what chlamydia is. Chlamydia is a sexually transmitted infection caused by chlamydia. According to statistics, this disease is very common throughout the world.

Types of chlamydia

To determine a specific infection, it is necessary to conduct a blood test for antibodies to chlamydia.

All chlamydia are divided into several types:

• Chlamydia psittaci - mainly causes disease in birds. But scientists have definitely proved that all these stamps can be transmitted to people. In humans, this species is capable of causing pneumonia, pyelonephritis, and arthritis. Thus, the species is transmitted from a sick bird to a person using the airborne route.
• Chlamydia psittaci is currently very little studied. The source is also animals, namely cattle. Scientists have not yet identified that this group of chlamydia is transmitted to humans.
• Chlamydia pneumoniae - capable of causing infection in both animals and humans. It is transmitted only from sick person to person. Mostly adults are infected. This species is capable of causing acute respiratory diseases (mainly with damage to the bronchi). Ways of transmission: airborne and airborne. Scientists have practically proved the theory that this group is capable of causing bronchial asthma.
• Chlamydophila abortus - This group calls for initiation in animals. Mostly sheep. In practice, there are cases when a pregnant woman has contact with an infectious animal (sheep), then unfortunately a spontaneous abortion may occur.
• Chlamydophila felis - This group mainly infects domestic animals such as cats. It proceeds in the form of rhinitis and conjunctivitis in an animal. It can also be transmitted to humans and cause conjunctivitis.
• Chlamydophila caviae - for the first time this group was identified in the guinea pig.
• Chlamydia trachomatis is a species found in humans. The carriers of the infection are insects. Infection occurs through: mucous membranes, dirty hands, eye rubbing. Infection of the eyes results in scarring that can lead to loss of vision.

There is also a classification of antibodies in the diagnosis. For example:

• IgM antibodies. Detected in the acute phase of infection. These antibodies indicate the progression of the disease. They can talk about an exacerbation of the disease. They are detected after infection with chlamydia on the 5th day. Then gradually the indicators decrease.
• IgM antibodies. They appear on the 14th day from the day of infection. Indicate the presence of an infection that is well "hidden" in the body. With proper treatment, only by the 4th month the credits go away. If the indicators do not decrease, then this indicates that the infection has most likely entered the chronic phase.
• IgG class. You can see in the blood at the 3rd week of the disease. It can stay in the body for more than one year. In pregnant women, this type of antibody crosses the placenta to the baby.

How do you do a blood test for antibodies to chlamydia

Basic principles of conducting research. DNA methods

There is a group of people who should be tested for chlamydia. These include:

• persons who have had unprotected sexual contact with a potentially dangerous partner;
• if a man or woman was first diagnosed, then it is necessary to examine the sexual partner;
• women diagnosed with infertility (more than 2 years);
• women who have a history of: cervical erosion, chronic adnexitis;
• women who have a permanent non-carrying of a child, premature birth, polyhydramnios.

To detect this infection, the patient's biomaterial is needed. The material can be:

• vaginal contents;
• secret of the prostate;
• sperm;
• blood;
• urine.

Research types:

1. Cytological analysis. For this study, it is necessary to take a scraping from the vagina, a secret of the prostate, or a scraping from the urethra. The material is dyed with special dyes. Chlamydia dyes give reactions to these dyes and become well visible through a microscope. The study is effective only in the acute phase.
   The effectiveness of the study is no more than 12%.
2. RIF and PIF. For research use any material that was taken with a scraping. The material is treated with special antibodies, which then react with chlamydia. Then, with the help of a fluorescent microscope, chlamydia shine either green or yellow-green.
   Good for acute phase or chronic disease. The research method very often gives a false positive result.
   The efficiency of the method is about 50%
3. ELISA. The study is based on the method of indirect detection of bacteria. This technique allows both to determine the presence of infection in the body, and to identify the pathogen. In addition, the study helps to determine the effectiveness of the prescribed treatment.
   The accuracy of this method is about 70%.
4. . Based on the detection of chlamydia DNA. The study itself lasts no more than 2 days. Any biomaterial (blood, semen, vaginal contents, urine, etc.) can serve as a material for research.
   The study has a 100% result. But there are false positive cases, but this happens when the material sampling process has been violated.
5. cultural method. In this method, the test material is placed in a special environment and sent to a thermostat. The material for the study can be a scraping from the vagina, urethra, prostate or conjunctiva of the eye. Where, if there is an infection, it begins to multiply. This technique helps to identify the pathogen and choose the right treatment. The study can take a long time, up to 7 days.
   The efficiency is about 90%.
6. Express diagnostics. The basis includes special kits that give results in 10-15 minutes.
   The accuracy of this study is not more than 25%.

Blood test for antibodies: interpretation of the results

Antibodies to chlamydia in the blood begin to grow rapidly in the acute phase of the disease. After recovery, antibodies gradually begin to decline. In cases of re-infection, the level of antibodies can increase sharply again.

• IgA positive, 1:5, IgG positive, 1:40. These results indicate the presence of infection in the body. Treatment is needed.
• IgG - positive, 1:10., IgA negative. These results indicate the immunity in the body after suffering chlamydia.
• IgA 1:5, normal - not detected. IgG 1:5, normal - not detected. These results indicate a chronic infection in the body.
• Chlamydia C. trachomatis (antibodies IgG-MOMP+pgp3) positive >1:40. This result is considered to be false positive. Usually an additional study is prescribed.
• Titer iga. If the infection is present in the body, then the titer iga can be detected in the blood. If its indicators are greatly increased, then this indicates an acute stage of the disease or an exacerbation of the chronic stage. Without treatment, the body will not be able to create a protective reaction. With proper treatment, the value of titers decreases. Often, additional studies are prescribed to make an accurate diagnosis.
• Igm titer These titers increase in the acute stage of the disease. Also, increased rates indicate active reproduction and vital activity of the infection. Indicators indicate the need for urgent treatment. This titer can be recognized in the blood no earlier than 21 days after infection.
  Titer readings can provide a good picture of the correct treatment and effectiveness of antibiotics. High rates of this titer during pregnancy indicate a high risk of infection of the child.
• Titer igg. The titer can be seen 3 weeks after the infection enters the body. Remains in the body for life. It is not possible to make a diagnosis based on this titer. Since the developed antibodies are a protective reaction of the body.

Table of test results for chlamydia

Blood test during pregnancy

A pregnant woman should have a special approach and attention. A blood test for chlamydia during pregnancy makes it possible not only to recognize the presence of infection in the body, but also the risk of infection of the fetus. In any case, with a positive result, treatment is necessary. Treatment must begin immediately. This may reduce the risk of fetal infection.

The infection itself is dangerous during pregnancy in that the infection can provoke:

• miscarriage;
• premature birth;
• infection during childbirth;
• congenital pathologies of the fetus.

Also, do not forget that during pregnancy there are often false positive results. To make an accurate diagnosis and prescribe treatment, it is recommended to conduct at least two blood tests.

Treatment is prescribed both local and general. Venous blood is used for analysis.

Analysis transcript:

• IgM negative and IgG negative - negative result, no infection in the body.
• IgM positive and IgG negative or positive - these indicators indicate an absolutely “fresh” infection. Urgent treatment required.
• IgM negative, and IgG have a certain titer. The results speak of the once transferred disease. It can also indicate the presence of a chronic infection in the body.

Chlamydia causes a number of diseases that have symptoms similar to other pathologies. The infection is transmitted from animals, birds and infected patients.

Chlamydia are resistant to the external environment up to 48 hours. Their death can be achieved by boiling for at least two minutes or by treatment with antiseptic agents.

Types of chlamydia depend on many factors. Diseases such as ornithosis and conjunctivitis occur when Chlamydia psittaci is ingested.

It becomes a source of chlamydial conjunctivitis, nasopharyngitis and otitis media in infants. Men and women suffer from urogenital chlamydia, proctitis, cholecystitis. The infection can cause trachoma.

It affects the respiratory tract, the cardiovascular system suffers. The infection develops various diseases, such as pneumonia, bronchitis, asthma and other pathologies.

Features of chlamydia is that the incubation period proceeds without pronounced symptoms, ranging from seven to twenty days.

Even in modern medicine, which does not stand still, but develops with the times, it is difficult to diagnose chlamydia in the human body.

Diagnosis is carried out by several methods prescribed by a specialist, depending on the gender of the person, age and symptoms with which the patient turned to the doctor.

In our time, the following methods are popular, described below, aimed at identifying a person.

Express or mini tests diagnosed with chlamydia. With their help, you can determine the infection at home.

You can buy such tests at pharmacy kiosks.

The main line of the diagnostic method is the method of immune chromatography.

When chlamydia gets on the test sensitive part, microorganisms combine with antibodies and change the color of the test strip.

The probability that the test will truly diagnose the presence of an infection in the body is low, only 15-40%. Therefore, experts do not advise trusting this diagnostic method.

If a person is symptomatic or knows they have been in contact with an infected patient, it is best to seek the help of a professional for a complete evaluation.

(microscopy) is another method that is popular. In the weaker sex of mankind, a smear is examined from the cervix, vagina, urethra during examination by a gynecologist.

A swab is taken by a urologist from the urethra or during prostate examination.

The technique came to us a long time ago, but even today it is popular in medicine. It is easy to perform, quickly and inexpensively for the patient determines the presence of chlamydia in the body.

But, unfortunately, only 15-35% of the method can determine the presence of infection. You should not refuse the procedure, it helps to identify inflammation and diagnose the presence of chlamydial disease.

The presence of leukocytes in a smear in the presence of chlamydia does not always increase, there are times when their number is normal.

Difficult diagnostic methods include immune fluorescence reaction.

Only a professional laboratory assistant who has access to sophisticated equipment can diagnose in this way.

There are a small number of such specialists today, which does not have the ability to distribute this technique in the provinces and small towns and villages.

Serological method belongs to the standard. It requires special antibodies that bind to chlamydia. After combination they are identified.

The method is simple to perform, the diagnosis takes a short period of time, but the result is not true, often the diagnosis leads to false readings.

It detects not an infection, but antibodies to it, which have three types of IgG, IgM, IgA. Low sensitivity is the main disadvantage of this technique.

Another disadvantage is the detection of infection only 25-35 days after entering the body. Having ease of use, the inexpensive financial side of the technique is still used extremely rarely.

DNA methods

Tests are given when the patient has another infectious pathology, sexually transmitted. In the case when the partner had casual sexual relations, or the partner complains of symptoms similar to chlamydia. Also, if during a routine examination, inflammatory processes of the cervix are revealed.

To check the presence or absence of chlamydia in the body in the laboratory should be in the antenatal clinic or other medical institution.

Home testing is also possible, but it's important to know that it's only about 25% true on average.

Turning to a specialist in time, each patient has the opportunity to endure the disease without complications and overcome the infection in a short period of time without large financial costs.

What biomaterial can be used for research

Blood from a vein is a biomaterial for research. When taking tests in the laboratory, you should prepare your body so that the result is true.

Blood from a vein should be taken on an empty stomach, since eating food, or even a cup of tea in the morning, will not give a real result.

In order for the tests to be accurate as a result, one should limit, or not eat at all, fatty, fried, smoked foods three days before donating blood from a vein. Eliminate alcohol two weeks before donating blood. It is recommended not to smoke on the day of the test.

To detect the presence of chlamydia, urine can be a biomaterial. When you pass it for a day, you should abandon sexual relations. It is advised to collect the morning portion of urine.

In the case of a smear or scraping, which is another biomaterial, sexual intercourse should be abandoned for three days. It is better not to go to the toilet three hours before delivery. A smear is recommended to be taken on the first day after the end of menstruation. There are cases when the analysis is taken from seminal fluid.

Attention: in rare cases, material from the joint cavity is used, which is secreted by the synovial membrane.

In this case, the sterility of the joints should be prepared.

Important: 14 days before the delivery of the biomaterial, you can not take antibacterial drugs.

Deciphering the analyzes: norm indicators

A professional laboratory assistant can correctly collect tests for the presence of chlamydia. For this, special equipment and reagents are used.

When the study is completed, the test results are given to patients and they should be consulted by a doctor who will correctly read the result and prescribe the correct treatment.

Chlamydia igm are the first to be determined already on the first day after the bacteria enter the body. After that, anti chlamydia trachomatis iga appear, which signal the progression of the disease.

Often patients ask if chlamydia trachomatis igg is positive, what does it mean.

Experts advise to seek full clarification from professionals, arguing that positive IgG indicates a chronic form of the disease.

Antibodies igg to chlamydia trachomatis can be calculated already on the twentieth day of the functioning of the infection in the body.

When the result of anti-chlamydia trachomatis lgg is positive, immediately contact a specialist for competent treatment, otherwise chlamydia will move to other organs and will be able to actively spread.

In the event that antibodies to chlamydia trachomatis igg are positive, you should not give up, the main thing is to follow the correct treatment regimen and choose the right drugs.

Antibodies to igg to chlamydia trachomatis igg transcript must be read correctly by a laboratory assistant or doctor. Studies do not always have the right result the first time. It is advised to take tests several times in order to understand the type and form of the disease.

It is important to know that chlamydia trachomatis igg antibodies show the correct result 20 days after infection.

A blood test for antibodies to chlamydia c trachomatis igg to momp pgp3 half-titer ifa indicates an active infectious process.

In this case, at least two types of antibacterial drugs should be used. In parallel, funds are prescribed for the intestines and the immune system.

Chlamydia trachomatis- what it is, if found in the analyzes, can be explained by a gynecologist, urologist, venereologist.

You can find information on the Internet, but every number and letter matters, so professionals will understand different combinations more deeply.

For example, anti chlamydia trachomatis iga can only appear in the human body.

The coefficient of positivity of the norm for chlamydia is 0-0.84. Antibodies to chlamydia in the blood, the norm shows a negative result.

When anti chlamydia trachomatis igg positive, iga negative, it means that the infection is recent and can be cleared from the body in a short period of time by the methods recommended by a professional.

General information about the study

Chlamydia trachomatis, IgG, are antibodies (immunoglobulins, immune factors) that are produced during chlamydia infection.

Chlamydial infection, or chlamydia, is a collection of diseases that are caused by microorganisms from the genus Chlamydia.

The life cycle of chlamydia consists of two phases. The first phase is extracellular, when chlamydia are in a spore-like form and are called elementary bodies (they are insensitive to antibiotics). After penetrating inside, chlamydia cells turn into reticular bodies - a biological form that actively reproduces; during this period, chlamydia are sensitive to antibiotic therapy. This feature explains the tendency of this type of infection to a long chronic course.

Four types of chlamydia cause diseases in humans, one of them is Chlamydia trachomatis . This species has several varieties (serotypes), each of which is prone to damage to a particular organ. Chlamydia trachomatis infects certain types of cells that cover the lining of the urethra, the inside of the cervix in women, the back of the throat, the lining of the rectum, the conjunctiva of the eyes, and the respiratory tract in children during their first months of life.

Infection with chlamydia occurs as a result of direct contact of the mucous membranes with the pathogen, usually during unprotected intercourse. Newborns can become infected during the passage of the birth canal.

The incubation period from the moment of infection to the appearance of the first symptoms of the disease lasts from 7 to 20 days or more. Sometimes visible signs do not develop. This is either an asymptomatic carriage, or cases when the symptoms of the disease are invisible, but the structures and functions of the tissues are slowly impaired (persistent form of the disease).

In women, chlamydial infection most often occurs in the form of inflammation of the cervical canal, from where it passes into the uterine cavity and fallopian tubes. Inflammation of the fallopian tubes (salpingitis) is the most common complication of chlamydia and can lead to blocked fallopian tubes and eventually infertility or tubal (ectopic) pregnancy. The peculiarity of chlamydia of the uterine appendages is the tendency to the absence of specific symptoms of the disease and a long course. In some cases, the infection spreads higher to the abdominal organs.

In men, chlamydia can be present as an inflammation of the urethra (urethritis), vas deferens (epididymitis). Sometimes inflammation of the prostate gland (prostatitis) occurs.

Between 5 and 20% of pregnant women have chlamydial infection of the cervical canal. Approximately half of the children who are born to them become infected during childbirth. Half of infected children develop chlamydial conjunctivitis, 10% develop pneumonia.

During sexual intercourse, chlamydial infection can cause an acute inflammatory disease - lymphogranuloma venereum. As the disease progresses, the lymph nodes increase and well-being is disturbed. In the future, complications associated with changes in the genitals and rectum are possible.

Infection with chlamydia is accompanied by the production of antibodies (immunoglobulins) in the body: IgM, IgA, IgG. The production of each of them is associated with a certain stage of the infectious process, so that their appearance and quantity in the blood can be used to judge the stage of the disease.

Antibodies of the IgG class occur 3-4 weeks after the initial infection with chlamydia and continue to be detected throughout the disease, as well as for a long time after recovery. Thus, a positive IgG test result indicates that chlamydia infection occurred at least 3-4 weeks ago.

What is research used for?

• To determine the stage of the disease with symptoms of chlamydial infection.
• To establish the fact of infection with chlamydia in the past (as a clarification of the causes of diseases that may be the result of chlamydial infection: infertility, ectopic pregnancy).

When is the study scheduled?

• With symptoms of chlamydial infection. In women, this is discharge from the genital tract, burning, itching in the genital area, pain in the lower abdomen. In men - burning during urination, discharge from the urethra, pain, itching in the genital area.
• If you want to establish the stage of chlamydial infection.
• If it is necessary to establish the fact of infection with chlamydia (for diseases that may be the result of chlamydial infection: infertility, ectopic pregnancy.

Chlamydia trachomatis infections are a common cause of inflammation of the reproductive organs, which can lead to infertility or pregnancy complications.

Chlamydia is a Gram-negative, intracellular bacterium.

After entering the body, it attaches to host cells, then penetrates them and multiplies, after which it spreads through the bloodstream.

One of the indicators of the presence of bacteria in the body is the presence of antibodies that appear after infection with Chlamydia trachomatis.

Depending on the type of antibodies, as well as their concentration, it is possible to draw a conclusion about the staging of the infection and how long the patient has been a carrier of the disease.

To obtain this information, various laboratory tests are used, among which there is an analysis for titers for chlamydia.

What are antibodies to chlamydia trachomatis

Antibodies, also known as immunoglobulins, are proteins produced by the body's immune system when it is invaded by antigens - foreign bacteria.

After infection, the immune system begins to actively defend itself and fight foreign microorganisms, which leads to the development of antibodies.

In laboratory diagnostic practice, the number/concentration of antibodies is indicated by the titer.

The titer of Chlamydia trachomatis is sometimes expressed only by the denominator, for example, 1:20.

Lab testing for chlamydia

Diagnosis of Chlamydia trachomatis infection is most often done by measuring the levels of IgM and IgG immunoglobulins in the blood.

And also by detecting the presence of microorganisms in the smear.

As a rule, a smear is collected with a special brush on the transport medium, from the vulva, cervix or urethral canal.

In a blood test or smear, chlamydia can be detected by the following methods:

• Immunofluorescence reaction (RIF). It is a versatile method in which a specific protein is labeled with an antibody (immunoglobulin) and visualized with a dye molecule. Advantages: fast process with high sensitivity. Disadvantages: high equipment costs, non-specific reactions are possible (depending on the test material and the quality of antibodies).
• smear microscopy. It is not considered as the most informative method for diagnosing STDs, but it allows you to determine the presence of an inflammatory process and identify some specific pathogens. It also allows you to determine the state of the microflora of the urogenital tract.
• Enzyme immunoassay (ELISA). It is used to detect specific proteins in a test material using polyclonal or monoclonal antibodies coupled to a suitable enzyme. Allows you to detect IgG, IgM, IgA - immunoglobulins. It is prescribed for the diagnosis of many diseases, mainly of viral and bacterial origin.
• Polymerase chain reaction (PCR). It is a method by which any DNA fragment can be duplicated in length from several to several hundred thousand nucleotides. This is the most sensitive and informative way to detect bacterial infections. Using PCR with 98% accuracy, chlamydia can be detected in the urogenital smear (blood PCR for chlamydia is not performed). The main advantage: the accuracy and speed of obtaining results (you can get a test report after a day).
• Bacteriological culture. The most accurate method for the analysis of chlamydia, in 99% of cases shows an accurate result. Bacteriological seeding is carried out by sowing the material on nutrient media. Additionally, the analysis allows you to determine the sensitivity of identified microorganisms to various types of antibiotics.

In diagnostic medicine, there is no 100% method for detecting infections, therefore, in order to obtain the most accurate result, a doctor may prescribe several types of analysis.

Deciphering the results of tests for chlamydia

In the process of interpreting the results, the positivity coefficient for Chlamydia trachomatis is taken into account.

If the value does not exceed 0.9, this indicates a negative result - there is no chlamydia.

Also, this value can indicate an effective and successful therapy.

In this case, the titer for chlamydia antibodies will be no more than 1:5.

With a positive result, the readings will start from 1.1, which will indicate infection no more than 20 days ago.

Also, similar results can be obtained immediately after treatment, so it is recommended to take tests 14 days after completion of therapy.

The titer of chlamydia in the blood tends to increase in the acute course of infection.

In the case of remission or complete cure, the titer decreases.

If the patient received results in the form of indicators from 09 to 1.1, the tests are repeated.

In this case, the values ​​are regarded as doubtful.

Repeated tests are carried out after 5-6 days.

The norms of titers for chlamydia should not exceed 1:10.

Antibodies to chlamydia trachomatis and their significance

Antibodies- Immunoglobulins allow you to determine the duration of the ongoing infection in the body and its staging.

There are following types antibodies to chlamydia in the blood:

• Immunoglobulin A (IgA). The main physiological role of IgA is to participate in immune reactions on the mucous membranes. The amount of IgA synthesized in the human body during the day is greater than that of all other immunoglobulins combined. Although the concentration of this immunoglobulin in the blood plasma is low, the vast majority of it is secreted on the surface of the mucous and serous membranes. A spontaneous increase in titer will indicate an exacerbation of chlamydia. An increase in IgA will be noted 8-12 weeks after infection.
• Immunoglobulin M (IgM). First-line immunoglobulins, secreted early in B-cell immunity, eliminate pathogens before sufficient IgG is produced. Receiving a positive response during the diagnosis will indicate a rapid infectious process. Antibodies of the IgM type appear 20 days after infection with chlamydia, and a decrease in indicators does not always indicate recovery.
• Immunoglobulins G (IgG). It is an immune protein produced by cells of the immune system - plasma cells, which are a type of B-lymphocyte. IgG antibodies are very specific because they are always directed against a specific antigen and are mainly produced in the later stages of the immune response, replacing less specific IgM antibodies.

Antibodies Igg to chlamydia trachomatis can be detected 2 weeks after infection.

Upon receipt of diagnostic results in the form of Igg (+) and Igm (+), it is necessary to begin treatment of chlamydia trachomatis.

Antibodies to chlamydia in the form of Igg (+), Igg (-) indicates that the body has had an infection.

In case of elevated IgG levels, the test should be repeated after 3 weeks.

Positive Igg for Chlamydia trachomatis

If the analysis showed a positive result of IgG antibodies to chlamydia, then the patient is infected - the bacterium Chlamydia trachomatis is in the body.

The main route of transmission of the infection is unprotected sexual contact; the disease is rarely transmitted by household means.

Briefly about chlamydia trachomatis

Chlamydia trachomatis is the most common microorganism that causes inflammation of the female genital organs, infertility and some pregnancy complications.

Chlamydia is a very insidious disease because it is often completely asymptomatic.

Women sometimes experience vaginal discharge, pain, or burning when urinating.

As mentioned earlier, chlamydia is caused by the microorganism Chlamydia trachomatis.

Usually the disease is transmitted during sexual intercourse and oral or anal sex.

In addition, the infection can be transmitted during childbirth, from mother to child.

This situation is very dangerous for the newborn, as it can cause an eye infection and pneumonia.

What are the consequences of an undiagnosed and untreated chlamydial infection?

• Infertility. A chlamydial infection can cause the fallopian tubes to become inflamed, causing them to narrow. In a narrowed fallopian tube, fertilization cannot occur, and if fertilization occurs, the cell remains in the narrowed fallopian tube, causing an ectopic pregnancy.
• Adnexitis. It is an inflammation of one or more often two fallopian tubes. Inflammation of the tubes is usually acute, with fever and pain in the lower abdomen. This infection can spread to the ovaries or peritoneum.
• Reiter's syndrome. Combines inflammation of the urethra, joints and conjunctiva.
• Urethritis. Infection of the urethra.

Chlamydial infection is also considered one of the possible factors influencing the development of cervical cancer.

In addition, pregnant women infected with chlamydia significantly increase the risk of miscarriage.

Every sexually active person should be tested for Chlamydia Trachomatis at least once a year.

Some doctors even say that such tests should be done every six months.

Until now, the diagnosis for the presence of chlamydia was based on the so-called bacterial culture (smear), which is taken from the cervix, vagina and urethra.

However, the most reliable, but also quite non-budgetary method for detecting chlamydia is genetic testing using PCR, performed in specialized laboratories.

Infections that are not accompanied by complications are quickly and effectively cured with antibiotics.

However, it should be remembered about the simultaneous antibiotic therapy of both partners.

Titer to immunoglobulins of chlamydial infection

What do the detected titers for chlamydia mean?

In microbiology, the titration method is often used to determine the concentrations of microorganisms in a biological material being tested.

In a way, this is a quantitative indicator with which you can determine the presence, as well as the concentration of the level of antibodies to chlamydia.

Immunoglobulins Igg, Igm, Iga to chlamydia trachomatis are determined during the ELISA analysis.

An increase in titer is noted with an active protective process of immunity in response to the penetration of Chlamydia trachomatis into the body.

In laboratory diagnostics, there are several results that can be obtained during testing of biological material for chlamydia:

• Immunoglobulins (antibodies) were not detected. This conclusion indicates the absence of an infectious process provoked by the bacterium Chlamydia.
• Antibodies Igg to chlamydia trachomatis low titer, Igm high (positive). The result indicates an ongoing disease in an acute form and a relatively recent infection.
• IgM titer is low, IgG is high. This result indicates a chronic course of infection. With such a result, such a phenomenon can be observed as: there are antibodies in the blood to chlamydia, but there are no bacteria in the smear. This is due to the minimal activity of the pathogen in the genitourinary tract.
• Immunoglobulins IgG and IgM have equally high titers. This indicates an exacerbation of the pathological process, where the infection was more than four weeks ago.

Without fail, when prescribing an ELISA analysis, a study is carried out aimed at detecting Chlamydia on the mucosa of the urogenital tract.

Such a set of diagnostic measures is important to determine the most effective treatment for the infection.

Chlamydia trachomatis: norm of Igg and Igm titers

It should be noted that the presence of low titers can be observed even in the absence of an infectious process.

This phenomenon is rather difficult to explain, but is associated with some features of the immune system.

Patients should pay attention to the following results:

1. The Igm titer is considered positive when its concentration is 1:200 or more.
2. An Igg titer is considered positive at a concentration of 1:10 or more.

In the case when the titers are rapidly increasing, we are talking about the presence of an active process in the genitourinary system.

This infection activity can cause values ​​in excess of 1:3000.

To confirm the activity of chlamydia in the urogenital tract, it is recommended to conduct a study of smears by the PCR method.

Detection of antibodies to chlamydia during pregnancy

The detection of Igg to chlamydia trachomatis during pregnancy, to put it mildly, can lead a woman into a state of shock.

This is not surprising, because medical treatment is practically excluded due to the presence of side effects.

And the lack of therapy can cause premature birth and inflammation of the membranes.

Important! The presence of antibodies in the body will not always mean the presence of an infection or its acute course.

You should know that after the end of drug therapy for chlamydia, antibodies in the body can be observed for several more years.

Thus, a positive IgG conclusion suggests that the patient had already had chlamydia at some time.

In this case, it is important to pay attention to antibodies of the IgM type.

If they could not be detected, then unrest can be excluded.

However, it must be remembered that ELISA, like any other type of research, can give erroneous results associated with various factors.

To obtain a complete and accurate diagnosis, PCR is recommended, which can detect the DNA of the pathogen.

If the presence of Chlamydia trachomatis in the body is confirmed, you should not panic.

The first thing to do is discuss your condition with your gynecologist to find out which antibiotic is best for this situation.

The doctor may prescribe an antibiotic as a single dose or for a week.

In most cases, antibiotic therapy alone is sufficient to treat the infection.

The partner should be treated at the same time as the pregnant woman, and both should abstain from sex for a week after the end of therapy.

After treatment, your doctor will order another test for chlamydia in three or five weeks.

This will determine how effective the therapy was.

The main risk of chlamydia during pregnancy is the possibility of passing the disease to the baby during childbirth.

If chlamydia is treated before delivery, the baby is safe.

Chlamydia trachomatis in children

The detection of Igg type antibodies to chlamydia trachomatis in a child of the first year of life is in many cases associated with maternal immunity to infection.

This type of immunoglobulin has the ability to penetrate from the mother's blood into the blood of the fetus, through the structure of the placenta.

Diagnosis of antibodies in a child's tests requires additional laboratory testing.

To clarify the diagnosis, a PCR study is performed.

Reducing the titer of chlamydia after treatment: when and how it happens

When do blood titers disappear after chlamydia treatment?

How quickly the titers fall depends on the type of antibody. So, IgA and IgM decrease quite quickly, after 10 days the study may show their absence.

Immunoglobulin IgG refers to antibodies responsible for a long-term immune response.

Therefore, after treatment, for another 4-9 months, and sometimes several years, IgG can be in the blood.

Be aware that chlamydia increases the risk of contracting other sexually transmitted diseases, such as gonorrhea or HIV.
