Why This Test Is Done

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 may also be used during pregnancy to assess risk or for diagnostic confirmation in certain cases.

What to Expect Before the Test

No special preparation is needed. A blood sample is typically taken from a vein in your arm. If you’re pregnant, your provider may ask for additional precautions, such as timing around your menstrual cycle.

What the Test Results Mean

Positive results suggest you have antibodies to HSV, meaning you’ve likely been exposed to the virus at some point. Negative results indicate no detectable antibodies, but this doesn’t always mean you’re definitively free of infection—other tests may be needed for confirmation.

Possible Side Effects

Most people experience mild discomfort or bruising at the injection site. Rarely, there may be slight swelling or redness.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test plays a key role in diagnosing genital herpes, guiding treatment decisions, and managing risk for pregnant individuals. Antibody presence helps confirm past infection but doesn’t always indicate active disease. It can also inform preventive measures, such as condoms or antiviral medications, to reduce transmission.

Frequently asked questions

How long does it take to get results from this test?
Results are usually available within 1 to 2 business days, depending on lab processing times. Your healthcare provider will discuss the findings with you.
Can I still have sex while waiting for my results?
Yes, but it’s important to use protection (like condoms) to prevent spreading the virus, even if you’re unsure of your status. Always follow your provider’s guidance.
Does this test differentiate between HSV-1 and HSV-2?
No, this test detects antibodies to both types of HSV but doesn’t specify which type you have. Additional testing may be needed for subtype confirmation.
