Gonorrhea (Neisseria gonorrhoeae) Antibody Screening by Immunofluorescence

What This Test Measures

The test detects specific antibodies (immunoglobulins) produced by your body in response to *Neisseria gonorrhoeae*, the bacterium responsible for gonorrhea. These antibodies appear after infection has cleared, often weeks to months later. The method used is immunofluorescence, which identifies the presence of these antibodies in a blood sample.

Why It Might Be Ordered

Your healthcare provider may order this test if you have symptoms suggestive of gonorrhea (e.g., unusual discharge, pain during urination) or if you’ve been exposed to the infection. It may also be used as part of routine screening in certain high-risk groups or after sexual exposure.

What to Expect Before the Test

No special preparation is needed. You may have a simple blood draw from a vein in your arm. If you’re pregnant or breastfeeding, inform your provider before testing.

What the Results Mean

A positive result indicates the presence of gonorrhea antibodies, suggesting past exposure. A negative result means no detectable antibodies were found at the time of testing. Results alone don’t confirm current infection; further testing (e.g., culture) may be needed for diagnosis.
