What This Test Measures

The test detects IgG antibodies against HSV-2, which your immune system produces after exposure to the virus. These antibodies can remain in your blood for years, even after symptoms have cleared.

Why It’s Done

Doctors may order this test if you have symptoms like sores, itching, or unusual discharge in the genital area, or if you’ve had multiple sexual partners. It can also be used for screening or during pregnancy to assess risk.

How It’s Performed

A blood sample is taken from a vein in your arm. The sample is then analyzed to detect HSV-2 antibodies using an immunoassay method.

What the Results Mean

A positive result means you have antibodies to HSV-2, suggesting past infection. A negative result means no detectable antibodies were found at this time, but it doesn’t guarantee you’re not infected.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How long does it take to get results from this test?
Results are typically available within 1 to 3 business days, depending on lab processing times. Follow-up with your healthcare provider for interpretation.
Can I have false positives or false negatives with this test?
False positives are rare but possible if you’ve had a previous infection or shared testing materials. False negatives can occur if the test is done too early after exposure or if the virus is actively replicating.
Does this test show if I currently have active herpes symptoms?
No, this test only detects antibodies, not active viral particles. If you have symptoms, your doctor may recommend additional testing or observation.
