What This Test Measures
The test looks for antibodies produced by your immune system in response to HSV. These antibodies can appear after infection, even if you don’t currently have symptoms. The method used may involve immunoassay to detect these antibodies in serum.
Why It’s Ordered
Your healthcare provider may order this test if you have symptoms of HSV (e.g., sores, pain, or recurrent outbreaks), have been exposed to HSV, or if you’re evaluating for transmission to others. It can also help confirm a diagnosis when other tests are inconclusive.
What to Expect Before the Test
No special preparation is usually needed. You may provide a blood sample during a routine office visit. If testing is done at a lab, follow any instructions provided to ensure accurate results.
What the Results Mean
Positive results indicate the presence of HSV antibodies, suggesting past or current infection. Negative results mean no detectable antibodies were found at the time of testing. Results may take several days to weeks to return, depending on the lab.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
This test helps diagnose HSV infection, assess risk of transmission, and guide treatment decisions. Antibody presence doesn’t distinguish between HSV-1 (often cold sores) or HSV-2 (often genital herpes), so additional testing may be needed for subtype identification.
A positive result means your immune system has detected HSV antibodies, indicating past exposure to the virus. This doesn’t necessarily mean you’re currently infected or have active symptoms, but it confirms you’ve been exposed. Your healthcare provider will discuss next steps, such as managing outbreaks or preventing transmission.
No, this test primarily detects past exposure. For diagnosing recent or active infection, other tests (like viral culture or PCR) may be used alongside antibody testing to confirm active HSV.
