Why Is This Test Done?

Your doctor may order this test if you have symptoms like sores, fever, or unusual infections that could be caused by HSV. It’s also used to confirm infection in people with recurrent outbreaks or specific medical conditions, like HIV, where HSV can be more severe.

What Does the Test Involve?

A sample of your bodily fluid (like saliva or lesion discharge) is collected and sent to a lab. The fluid is placed on a special medium where, if HSV is present, it will grow and be identified under a microscope or through further testing.

How Long Does It Take?

Results typically take 3 to 7 days, depending on the lab’s processing time. If HSV is detected, you may receive results sooner through rapid methods, but cultures often provide more detailed confirmation.

What Are Common Results?

A positive result means HSV is growing in the sample, indicating active infection. A negative result means no HSV was detected in the sample at the time of testing. Follow-up tests may be needed if symptoms persist.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why might my doctor want this test?
Your doctor may use this test to diagnose HSV infections, especially if symptoms are unclear or if you have a history of recurrent outbreaks. It can also help monitor infections in people with weakened immune systems or specific health conditions.
What does a positive result mean for my health?
A positive result confirms HSV infection and helps guide treatment options, such as antiviral medications to manage symptoms or reduce outbreaks. It doesn’t change your long-term risk but confirms the need for ongoing care if needed.
Can I get HSV from this test?
No, the test itself does not transmit HSV. The sample is collected safely, and the lab follows strict protocols to prevent contamination.
