What is the Chlamydia Trachomatis IgA Antibody Test?

The Chlamydia Trachomatis IgA Antibody Test measures IgA antibodies produced by the immune system in response to infection with Chlamydia trachomatis. IgA antibodies are often associated with active or persistent mucosal infection. This test supports the diagnosis of Chlamydia infection and may be used along with molecular tests and clinical evaluation.

Who should take this test?

• Individuals with symptoms of sexually transmitted infections (STIs).
• Women with pelvic inflammatory disease (PID) or infertility evaluation.
• Men with urethritis, epididymitis, or genital discomfort.
• Patients with suspected persistent or chronic Chlamydia infection.
• Individuals with high-risk sexual exposure.
• Doctor-advised evaluation of reproductive tract infections.

Preparation & Test Process

Understanding Your Results

Positive IgA antibodies may indicate a recent, ongoing, or persistent Chlamydia trachomatis infection.

Negative IgA antibodies suggest that no detectable IgA response is present, although very early infection or certain clinical situations may require additional testing.

Results should always be interpreted together with symptoms, medical history, and other laboratory tests such as Chlamydia PCR/NAAT or IgG/IgM antibody testing.
