Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like sore throat, mouth ulcers, or lesions that could be caused by HSV-1. It’s also used in certain situations, such as diagnosing recurrent oral herpes or evaluating immunocompromised patients for viral infections.

What to Expect During the Test

A swab is gently taken from your throat to collect cells and secretions. The swab is then sent to a lab for culture. This process is quick and usually painless, though you might feel mild discomfort.

How the Results Are Interpreted

If HSV-1 is grown in the lab, it confirms a current infection. A negative result means no active HSV-1 was detected in the sample at the time of testing. Results may take several days to a week to receive.

What the Results Mean

Positive results indicate active HSV-1 infection in your throat, which may require antiviral treatment. Negative results suggest no active infection was found, but HSV-1 can still be present without symptoms.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
