Herpes Simplex Virus Antibody Test (IgG) – Penis/Scrotal Fluid
This test checks for antibodies to herpes simplex virus (HSV), a common virus that can cause genital sores. Antibodies indicate past or current infection, even if symptoms are no longer present.
["Helps assess exposure to HSV, though symptoms may not reflect current infection status."]

What This Test Measures
The test detects IgG antibodies specific to HSV, which develop after infection. These antibodies can remain in your system for years, even after active outbreaks have resolved. This test is performed on fluid collected from the penis or scrotum, often during a clinical exam or swab procedure.
Why It’s Ordered
Doctors may order this test to evaluate HSV exposure in individuals with recurrent genital sores, sexual history concerns, or during pre-surgical evaluations. It’s not used to diagnose active infections but can help confirm past exposure.
How It’s Performed
A healthcare provider collects fluid from the penis or scrotum using a sterile swab or direct sampling. The fluid is then tested in a lab to detect HSV-specific antibodies. Results are qualitative (positive/negative) rather than quantifying antibody levels.
What the Results Mean
A positive result means you likely had HSV at some point, but it doesn’t indicate when or if you’re currently infected. A negative result suggests no detectable antibodies, meaning HSV exposure may not have occurred or antibodies are below detectable limits.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
This test is primarily used for screening or historical exposure assessment rather than diagnosing active infections. HSV can be transmitted even without visible sores, so discussing symptoms and sexual history is crucial for accurate evaluation.
No. If you have active genital sores, your doctor may recommend a different test, such as a viral culture or PCR test, to diagnose the current infection.
No. Antibody tests like this one don’t indicate active infection status. HSV can remain dormant, and antibodies don’t reflect whether you’re contagious at the moment.
