A herpes (HSV) test looks for signs of the herpes simplex virus. There is no cure, but medicines can help manage outbreaks. The test can be done using fluid from a sore during an outbreak or a blood sample if you have no symptoms. Results depend on the type of test and your health history.
Preparation and collection
You don't need any special preparations for a swab test or a blood test. For a lumbar puncture (if needed), you may be asked to empty your bladder and bowels before the test.
Understanding this test
Use the reference interval and units printed by the laboratory that performed the test. A result outside that interval is not a diagnosis by itself, and a result inside it does not rule out every condition. Your symptoms, history, medicines, timing, and related tests can change what the result means.
- A negative blood test result may occur if the test is done too soon after infection, before your body has made antibodies (up to three months).
- A positive blood test result cannot distinguish between a current active infection and a past infection.
- Swab tests may miss the virus if the sore is already healing or if the sample is not collected properly.
- At-home tests require you to collect and send a blood sample; talk with your provider to find out if at-home testing is right for you.
What to do next
Your provider will interpret your results based on your health history and symptoms. If you have HSV, treatment can help reduce outbreaks and control symptoms. Talk with your provider about HIV testing and other STI testing, and about steps to avoid spreading HSV to others.
