Had cultlure of lip-pos hsv1, and blood done-pos for hsv 1 neg hsv2/repeated blood test 3 months later results reversed neg 1 postive 2. doctor puzzled?

Details needed: The type of test is important here - figure out if testing was broken down to "igm" or "igg", and the exact timing of when the tests were done - that will help interpreting what 's going on. Why? Igm goes up in early infection , then drops when igg levels start to go up later after. Infection.

Possible lab error?: Always a possibitlity. Repeat test if needed. That said, does it really matter? Talk to your doctor about the treatment regimen available for each strain (same: anti-viral meds). It used to be hsv-1 was oral; hsv-2 genital. With increased oral sexual activity, the portal of infection becomes irrelevant. Cold sores (oral or genital) are recurrent infections and highly contagious.
