Anti Chlamydia Antibody Test- IgG

Anti chlamydia antibody IgG test measures the level of antibodies against Chlamydia trachomatis in the serum. Chlamydia trachomatis is a bacteria that is most commonly known to cause sexually transmitted infections (STI) in both men and women as well as newborns. Chlamydia usually spreads through anal, oral or vaginal sex. Newborns can contract Chlamydia during vaginal birth if the mother is infected. However, most cases of Chlamydia remain asymptomatic. Therefore anti chlamydia antibody IgG tests are required to detect the presence of infection.

The samples that are used for the diagnosis of Chlamydia include swabs of fluid from the cervix, vagina, throat, eyes or urine samples. A few of the common symptoms of chlamydia infection are a burning sensation during urination, rectal pain, vaginal bleeding and abnormal discharge from the vagina, rectum or penis. Untreated chlamydia infections can lead to serious conditions such as pelvic inflammatory disease (PID) and infertility.

Apart from the anti-chlamydia antibody IgG test, chlamydia detection can take place by other tests such as cell culture and nucleic acid amplification test. The testing method differs depending on the site of the infection and the samples that are provided by the patients.

Chlamydia infection is very common in India. Every year more than 1 million cases of Chlamydia are reported. Although most cases of chlamydia infection are asymptomatic, it can lead to serious conditions if left untreated. Chlamydia infections are mostly seen to impact fertility and cause ectopic pregnancies in women in India.

Other names of Anti chlamydia antibody IgG test

• Chlamydia antibody test
• Serum antibody test

What does the anti-chlamydia antibody IgG test detect and who it is prescribed for?

The anti-chlamydia antibody IgG test detects the presence of serum IgG antibodies against Chlamydia which helps to determine whether or not a chlamydia infection exists.

Few groups of people are advised to undergo the test at regular intervals for screening purposes. They are:

• Women who are sexually active and under the age of 25 years must be tested annually, while women above 25 years must be tested in three months as they are at increased risk of contracting Chlamydia.
• The test is also recommended for all pregnant women.
• Annual testing is recommended for sexually active men.
• Sexually active individuals with HIV must also be tested regularly.

Certain risk factors increase the chance of contracting chlamydia infection. These risk factors include:

• Sex with multiple partners.
• Sex with a partner who has been diagnosed with STI.

Testing is also prescribed when certain signs and symptoms are present. These are:

• Burning sensation during urination
• Abdominal pain
• Vaginal bleeding
• Abnormal discharge from the vagina, rectum or penis
• Rectal pain

Since Chlamydia can infect both men and women, both groups must be tested if any of the above risk factors or symptoms are present.

The results of the anti chlamydia antibody IgG test are reported as either positive or negative which indicates whether the infection has been brought about by Chlamydia or not.

A positive test indicates that a patient is currently infected with Chlamydia and needs to be treated with antibiotics. If a sexually active individual tests positive, their partner is also recommended to undergo the anti-chlamydia antibody IgG test.

A negative test indicates no chlamydia infection is present. However, if certain symptoms exist, the individual is prescribed tests for other infections.

Anti chlamydia antibody IgG test is a blood test that detects the presence of IgG antibodies against the bacteria chlamydia. If IgG antibodies are detected, it indicates the presence of active chlamydia infection, which then needs to be treated.

The results of the anti-chlamydia antibody IgG test can either be positive or negative. A positive result indicates the presence of chlamydia infection, whereas a negative result indicates their absence.

The test is recommended mostly for patients suffering from certain symptoms as well as those having risk factors that are mentioned above. The test is also prescribed at regular intervals for people having HIV and sexually active men and women, even if no symptoms are present. This is because most cases of chlamydia infection remain asymptomatic.

Anti chlamydia antibody IgG test is done using blood samples of patients. The blood is collected mostly from a vein in the patient's arms.

Test Preparation

No special preparation is required for the anti-chlamydia antibody IgG test; however, if the patient is undergoing antibiotic therapy, you must consult with their doctor to ensure whether the medication should be stopped before undergoing the anti-chlamydia antibody IgG test.

However, patients getting tested for anti-chlamydia antibody IgG test are recommended to avoid having sex with their partners until negative results are received

Test inclusions: what parameters are included?

The anti-chlamydia antibody IgG test includes only one parameter, which is the level of IgG antibodies against Chlamydia. If the level of IgG antibody is found to be high, it indicates current or recent infection with Chlamydia, while low IgG levels indicate the absence of chlamydia infection.

How frequently should you take the test?

Anti chlamydia antibody IgG test is not a routine test. The test is prescribed by doctors only when certain symptoms of chlamydia infection are detected in patients.

Testing is also recommended for patients who have been diagnosed with Chlamydia and are undergoing treatment. This helps to determine whether the treatment is effective against the infection.
