No specific preparation is required, but avoid using any creams, ointments, or lotions in the genital area on the day of testing.

This test is done to find out whether you have been infected with herpes simplex virus type 2 (HSV-2), the virus that most commonly causes genital herpes. It can help explain symptoms such as painful sores, itching, or burning in the genital area, and it can also give you answers if you are worried about a possible exposure even when you feel completely well. Knowing your status allows you and your healthcare provider to discuss treatment options and take steps to lower the risk of spreading the infection to others.

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 genital herpes. It can also be used to confirm a diagnosis in cases where symptoms are unclear or if you’ve been exposed recently.

The test detects signs of an HSV-2 infection in a sample taken from your body. Depending on the method your healthcare provider orders, the laboratory may look for the genetic material (DNA) of the virus, as with a PCR test, or for antibodies that your immune system produces in response to the infection. These laboratory methods are designed to be accurate and reliable, and they can distinguish HSV-2 from the closely related HSV-1 so your provider gets clear information about your condition.

The test uses a specialized molecular method (PCR) to identify tiny amounts of HSV-2 DNA in a swab sample collected from your genital area. This helps detect the virus even when symptoms are not present.

A sample is collected in one of two ways, depending on the type of test your provider orders. If you have an active sore or blister, your provider will gently swab the area with a soft sterile swab to collect fluid and cells. If a blood test is ordered instead, a small amount of blood will be drawn from a vein in your arm, usually at the inside of your elbow. Both procedures take only a few minutes and cause minimal discomfort.

A healthcare provider will collect a sample by swabbing the affected genital area. The sample is then sent to a lab for testing. This is usually done during an office visit or clinic visit.

After your sample is collected, you can return to your normal activities right away, and no recovery time is needed. Your results will be sent to your healthcare provider, who will contact you to review them and answer any questions. If the test shows that you have HSV-2, effective antiviral medications are available to manage outbreaks and reduce the risk of transmission. If your result is negative but you were recently exposed, your provider may recommend repeat testing in a few weeks.

After your sample is collected, you may receive results within a few days to a week, depending on the lab. If the test is positive, it means the virus is actively present in your genital area. If negative, it suggests no active infection at the time of testing.
