Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms like burning or itching during urination, sores around your genitals or mouth, or unexplained fever and fatigue. It’s also used to confirm a suspected herpes infection in people with recurring outbreaks or those who have been exposed.

How Is the Test Performed?

A small urine sample is collected, usually in the morning. The sample is then sent to a lab where it is cultured to detect the presence of HSV. This process may take several days to complete.

What Do the Results Mean?

A positive result means HSV was found in your urine, suggesting an active infection. A negative result means no HSV was detected, but this doesn’t always rule out infection if the sample was taken too early or if the infection is in a different part of your body.

What Are the Possible Outcomes?

If you have symptoms, a positive culture confirms herpes infection and guides treatment decisions. If you’re asymptomatic or have recurring outbreaks, this test may be part of monitoring to assess viral load or response to treatment.

Frequently asked questions

How long does it take to get results from this test?
Results typically take 3 to 7 days or longer, depending on lab processing times. Your healthcare provider will contact you once they have the outcome.
Can I take antibiotics for this test?
No, antibiotics are ineffective against viral infections like herpes. If you suspect an infection, avoid taking any medications without consulting your doctor first, as this may affect test results.
What if I have recurring herpes outbreaks?
If you experience frequent outbreaks, your doctor may recommend regular testing or other diagnostic methods, such as viral load testing or PCR, to monitor your infection better. Lifestyle changes, stress management, and antiviral medications can help reduce outbreaks.
