Why This Test Is Done
Your healthcare provider may recommend this test if you have symptoms like sores, pain, or unusual discharge in the genital area, or if you have recurrent outbreaks. It can also be used for screening, especially in high-risk groups like those with multiple sexual partners or a history of sexually transmitted infections (STIs).
What to Expect Before the Test
No special preparation is needed. You’ll provide a blood sample from a vein in your arm. The test is usually done in a lab setting and may take a few minutes.
What the Test Results Mean
A positive result means you have antibodies to HSV-2, suggesting past infection. A negative result means no detectable antibodies, but it doesn’t rule out current infection (since antibodies may take time to develop). If you’re concerned, discuss your symptoms and test results with your provider.
Possible Results and Next Steps
If you test positive, your provider may recommend further testing to confirm HSV-2 infection (rather than HSV-1) and discuss treatment options, such as antiviral medications. If you test negative but have symptoms, other causes may be investigated.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
HSV-2 is a common sexually transmitted infection that can cause painful sores and recurrent outbreaks. Antibody testing helps diagnose past infection, assess risk, and guide management. Early treatment can reduce symptoms and transmission.
