Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like sores, blisters, or unusual itching in the genital or anal area, especially if you suspect genital herpes. It can also be used to confirm a diagnosis after an initial herpes outbreak or if you have recurrent symptoms. Additionally, it may be part of testing for sexually transmitted infections (STIs) or if you have unexplained skin rashes in those areas.

How the Test Works

A small sample of skin from the affected area is collected and sent to a lab. The lab then grows the virus in a controlled environment to identify HSV-2 if present. This process can take several days to weeks to complete.

Sample Collection and Preparation

During the test, a healthcare provider will clean the affected skin area and gently scrape or swab a small portion of the lesion. The sample is then sent to a lab where it is cultured to detect the presence of HSV-2.

What to Expect After the Test

After the sample is collected, you may experience mild discomfort or stinging, but it usually resolves quickly. You should avoid applying lotions, creams, or ointments to the test area until further instructions from your healthcare provider.

Frequently asked questions

What does a positive result mean?
A positive result indicates the presence of HSV-2 in the skin sample, confirming a herpes infection. This means you have the virus and may spread it to others, even if you have no visible symptoms. Your healthcare provider will work with you to develop a treatment plan and provide guidance on managing the infection.
What does a negative result mean?
A negative result means the virus was not detected in the sample at the time of testing. However, HSV-2 can be difficult to detect during certain times of the infection cycle, so a negative result does not always mean you are not infected. You may need to retest or have other tests to confirm your status.
How often should I get tested for HSV-2?
If you suspect you have HSV-2 or have had multiple sexual partners, your healthcare provider may recommend testing. For individuals with recurrent outbreaks, testing may be done during or just after an outbreak. Regular testing is not typically recommended for everyone unless advised by a healthcare provider based on your risk factors and symptoms.
