Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like cold sores, recurrent mouth ulcers, or if you have been exposed to someone with HSV-1. It may also be used in certain research or screening contexts.

What to Expect Before the Test

No special preparation is needed. You will provide a saliva sample, usually collected by swabbing the inside of your cheek or mouth. This is a simple, non-invasive procedure.

What the Test Results Mean

A positive result means HSV-1 genetic material was detected in your saliva, indicating exposure to the virus. A negative result means no detectable genetic material was found at the time of testing. Results do not always indicate current infection status or severity.

Common Uses and Limitations

This test is primarily used for screening or research purposes rather than confirming active infection. It cannot distinguish between past infection and current infection. Results should be interpreted by a healthcare provider in the context of your symptoms and medical history.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a positive result mean?
A positive result suggests you have been exposed to HSV-1, but it does not always mean you have an active infection. HSV-1 can remain dormant in your body for years without causing symptoms. This test is often used in research or specific clinical scenarios rather than routine diagnosis.
Can this test detect active infection?
No, this qualitative test detects HSV-1 DNA in saliva, which may indicate past exposure rather than an active infection. For diagnosing active herpes, other tests or clinical evaluation may be needed.
How does this differ from a culture test?
This test identifies HSV-1 genetic material without growing the virus in a lab. Culture tests grow the virus to identify active infection, while this test provides a broader but less specific exposure assessment.
