What this test is
The Chlamydia Blood Test detects antibodies against Chlamydia trachomatis, the bacterium that causes chlamydia. It is typically used when a non-genital infection, such as lymphogranuloma venereum, is suspected. This test does not detect the bacteria directly and is not a substitute for standard genital chlamydia testing.
What it measures
- Chlamydia trachomatis antibodies — Reflects past or present exposure to the bacterium
- Antibody type (IgG or IgM) — May help distinguish between recent and past infection
- Antibody titer — Indicates the level of antibodies present, though values vary by lab
What the test involves
A blood sample is collected from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test when symptoms suggest a non-genital chlamydia infection or when other testing methods are not suitable. It is not routinely ordered for genital chlamydia screening.
Preparation
No special preparation is usually required, but follow the instructions provided by the collection lab. If you take medications or have other health conditions, ask the lab if any adjustments are needed.
How results are reported
Results are reported as positive or negative for antibodies, sometimes with a numerical value. Reference ranges and reporting methods vary by laboratory, so your results should be interpreted by a clinician in the context of your health history.
