Published: August 9, 2026Updated: August 16, 2026

This test detects antibodies to *Neisseria gonorrhoeae*, the bacteria responsible for gonorrhea, using a blood sample. It helps identify if your immune system has been exposed to the infection, even if symptoms aren’t present.

Why This Test Is Done

Your healthcare provider may order this test if you have symptoms of gonorrhea (e.g., unusual discharge, pain during urination) or if you’re at higher risk (e.g., sexually active, recent STI exposure). It can also be part of routine screening for sexually transmitted infections (STIs).

What to Expect Before the Test

No special preparation is needed. You’ll provide a blood sample, typically drawn from a vein in your arm. The process takes a few minutes, and you can resume normal activities afterward.

What the Test Results Mean

A positive result means antibodies to *N. gonorrhoeae* are present, suggesting past exposure. A negative result indicates no detectable antibodies, but this doesn’t rule out current infection—other tests (like culture) may be needed.

Common Causes of False Results

False negatives may occur if the infection was recent or treated. False positives are rare but can happen with cross-reactions in some immunoassays. Discuss results with your provider for interpretation.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This screening supports early diagnosis of gonorrhea, which can be treated with antibiotics. Untreated gonorrhea may lead to complications like pelvic inflammatory disease, infertility, or spread to other body parts. Antibody detection helps guide follow-up testing or treatment decisions.

Frequently asked questions

Will this test show if I have gonorrhea now?
No, this test only detects antibodies from past exposure. For current infection, your provider may recommend a culture or nucleic acid test.
Can I get this test at home?
No, this is typically done in a clinical lab using a blood sample. Home tests for gonorrhea usually involve urine or vaginal swabs, not blood.
How long does it take to get results?
Results are usually available within 24–72 hours, depending on lab processing times. Follow-up with your provider for interpretation.
