Neisseria gonorrhoeae Antibody (Serum) – Gonorrhea Immunoassay (Screen/Confirm)
This test detects antibodies in your blood that your immune system produces in response to *Neisseria gonorrhoeae*, the bacterium responsible for gonorrhea. It helps identify past or current infections.
["This test helps determine if you’ve been exposed to gonorrhea, even if you don’t have symptoms."]

What This Test Measures
The test looks for antibodies (proteins) your body makes when it fights off *Neisseria gonorrhoeae*. These antibodies can appear after infection, even if symptoms are mild or absent. The test uses an immunoassay method to detect these antibodies in your serum.
How the Test Works
Your blood sample is taken from a vein in your arm. The lab analyzes it to check for gonorrhea-specific antibodies. This is typically done using a sensitive immunoassay technique to ensure accuracy.
Why It’s Done
Doctors may order this test if you have symptoms of gonorrhea (e.g., painful urination, discharge, or pelvic pain in women), if you’ve been sexually exposed to gonorrhea, or as part of routine screening in high-risk groups (e.g., sexually active individuals). It can also help confirm a gonorrhea diagnosis when other tests (like culture) are unavailable or inconclusive.
What to Expect Before the Test
No special preparation is needed. You may have a slight bruise or discomfort at the injection site, but this usually fades quickly. Avoid alcohol for 24 hours before the test if possible, as it may affect lab results.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Positive results indicate past or current gonorrhea infection. However, a positive antibody test alone does not confirm an active infection—additional testing (like culture or nucleic acid amplification) may be needed to diagnose active gonorrhea. Antibody levels can decline over time, so repeated testing may be required for accurate monitoring.
