What Does This Test Measure?

A viral culture identifies whether HSV-1 is present by allowing the virus to multiply in a controlled lab environment. Unlike antibody tests, this method directly detects the virus itself, helping confirm active infection rather than past exposure.

Why Might You Need This Test?

Your healthcare provider may order this test if you have symptoms like sores, pain, or unusual discharge in the genital or mouth area, or if you have recurrent outbreaks. It’s also used to diagnose infections in newborns or during pregnancy.

How Is the Sample Collected?

A swab sample of vaginal secretions is collected during a clinical exam. The swab is sent to a lab where the virus is grown over several days to confirm its presence.

What Are the Possible Results?

Results can be positive (virus detected) or negative (no virus found). A positive result means active HSV-1 infection is likely. Results may take several days to weeks to complete.

Clinical interpretation

Frequently asked questions

How long does it take to get results from this test?
This test typically takes 3 to 14 days to complete, depending on lab processing times and whether the virus grows in the culture.
Can this test detect HSV-1 in other body fluids?
Yes, this test can be performed on samples from other areas (like the mouth or genital regions) depending on clinical need, but vaginal culture is most common for genital infections.
What if my test comes back positive?
A positive result means you have an active HSV-1 infection. Your healthcare provider will discuss treatment options, such as antiviral medications, and may recommend managing outbreaks to prevent complications.
