Thank you so much for your expertise and guidance, Doctor.
You have HSV-2, unquestionably. But your doc is wrong about the strength of the positive result. Yours is not 'exceptionally high', and the number says nothing at all about the duration of your infection. It could be anywhere from 6 weeks to many years. Your numerical result might vary over time, up or down, if you are ever retested--but there will never be any point in retesting. Once positive, always positive; and any change in the number will provide any useful information that you don't already know.
Now the important thing is to be on the lookout for symptoms. About 2/3 of people who didn't know they were infected, but who have positive blood tests, come to recognize typical (but mild) symptoms that they didn't notice before. Most of them notice such symptoms within 3 months. Avoiding sex when you have such symptoms can help protect your uninfected sex partners.
Good luck-- HHH, MD
