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 a history of genital herpes. It can also be used during pregnancy to check for HSV antibodies to prevent transmission to the baby.

What to Expect Before the Test

No special preparation is needed. The blood sample is typically drawn from a vein in your arm. If you’re pregnant, let your provider know about any medications or supplements you’re taking.

What the Test Results Mean

Positive results indicate the presence of HSV antibodies, suggesting past infection. Negative results mean no detectable antibodies, but this doesn’t rule out current infection—symptoms or other testing may be needed for confirmation.

Common Causes of Positive Results

A positive result could mean you’ve had HSV-1 or HSV-2 infection at some point, even if you’ve never had symptoms. It doesn’t distinguish between the two types of virus.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Positive results may prompt further testing to confirm HSV infection, especially if you’re pregnant or have symptoms. HSV can be managed with medication, and early treatment can reduce complications. Always discuss results with your healthcare provider for personalized guidance.
