Good to knowOne result rarely tells the whole story. Your provider looks at your results together with your symptoms, exam, and other tests.
What the test is
Swabbing a fresh sore is the most accurate test. Routine blood testing without symptoms isn't recommended.
Why it's done
- Blisters or sores on the genitals or mouth
Getting ready and what happens
- Get tested while the sore is new.
How the test is done
- A swab of the sore, or a blood draw.
What the results mean
Positive
Herpes is common and manageable. Antiviral medicine shortens outbreaks and lowers spread.
Questions to ask your provider
- What do my results mean for me?
- Do I need to repeat this test or have other tests?
Risks
A blood draw is very safe. You may have slight pain or a small bruise where the needle went in.
