Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like sores, fever, or flu-like illness that could be caused by HSV-1. It’s also used to diagnose infections in people with weakened immune systems or recurrent outbreaks.

What to Expect During the Test

You’ll provide a saliva sample, usually by swabbing your inner cheek or mouth. The sample is then sent to a lab for culture. Results may take several days to weeks, depending on lab processes.

Preparation for the Test

No special preparation is needed. Avoid brushing your teeth or eating/drinking for 30 minutes before the test if instructed, but this isn’t always required for a saliva culture.

What the Results Mean

A positive result means HSV-1 was detected in your saliva, confirming an active infection. A negative result means the virus wasn’t found in the sample at the time of testing, but HSV-1 can still be present without symptoms.

Clinical interpretation
