Chlamydia IgG and IgA Antibody Detection by Immunofluorescence (Serum)

Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like unusual discharge, pain during urination, or unexplained pelvic pain. It’s also used for screening in high-risk groups (e.g., sexually active individuals, pregnant women) or after exposure to *Chlamydia*.

What to Expect Before the Test

No special preparation is needed. You’ll provide a blood sample from a vein in your arm. The test uses serum (liquid part of blood after clotting).

What the Test Results Mean

Positive results indicate past or current infection. Negative results mean no detectable antibodies, but a negative test doesn’t always rule out infection if symptoms persist or exposure is high-risk. Follow-up testing may be needed.

Common Causes of False Results

False negatives can occur if tested too early after exposure or if the infection was mild. False positives are rare but may happen with other infections or autoimmune conditions. Discuss results with your provider for guidance.
