Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like sores, itching, or unusual discharge in the genital area, or if you have a history of herpes. It’s also used to diagnose HSV in people with no visible symptoms but a positive test history.

What to Expect During the Test

A swab is gently collected from a sore or lesion on your penis. The sample is then sent to a lab for microscopic examination to detect HSV DNA or viral particles.

Sample Collection Process

No special preparation is needed, but avoid washing the genital area with soap or lotions before the test. If you have multiple sores, swabs may be taken from each.

What the Results Mean

A positive result means HSV is present in the sample, confirming genital herpes. A negative result means the virus was not detected in this sample, but HSV could still be present in other areas or latent in your body.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
