A chlamydia blood test checks for antibodies your immune system makes in response to Chlamydia trachomatis, the bacterium that causes chlamydia. It is not the preferred test for routine screening; urine or swab tests are more common. A clinician may order it when infection is suspected but routine samples are not possible.
What it measures
- Chlamydia trachomatis IgG antibodies — Shows past or current exposure; a positive result does not prove active infection.
- Chlamydia trachomatis IgM antibodies — May suggest a recent or early infection, but timing can be unclear.
- Chlamydia trachomatis IgA antibodies — Sometimes checked to help assess ongoing infection, though it is not definitive.
Who it is for
A clinician may order this test when a person has symptoms or a known exposure, or when urine or swab testing is not practical. It is not a routine screening test for most people.
Preparation
No fasting or special preparation is needed. Tell your clinician about any antibiotics you are taking, as they may affect results.
Results and what they mean
Results are reported as positive, negative, or equivocal for each antibody type. A positive result means antibodies were found, but it cannot confirm active infection or show when exposure occurred. A clinician interprets results alongside symptoms and other tests. This is general information, not medical advice.
Requesting the Chlamydia Blood Test in California
Order online, choose a certified collection site in California, and review results through a secure portal. No referral is required, and orders are processed confidentially. With coastal metros, inland towns, and rural counties with very different access to testing, it pays to schedule your collection in advance.
Frequently asked questions
Is a blood test the best way to check for chlamydia?
Usually no. Urine or swab tests are preferred because they detect the bacteria directly. Blood tests look for antibodies and are less specific.
What does a positive result mean?
It means your immune system has made antibodies to chlamydia at some point. It does not prove you have an active infection now.
Can I get this test without symptoms?
Yes, but it is not routine. Talk with a clinician about whether it is appropriate for your situation.
How long does it take to get results?
Typical turnaround is 1 to 3 business days after the sample reaches the lab.
