If your HSV-1 blood test is positive but your HSV-2 blood test comes back negative, and you have no oral or genital symptoms, it can be challenging to determine if the HSV-1 infection is oral (O) or genital (G). The location of an HSV infection cannot always be pinpointed solely based on a blood test result.

To get more clarity on the specific location of your herpes infection, you may consider consulting with a healthcare provider who can perform further testing or evaluation. They might recommend additional tests such as viral culture swabs from suspected areas like the mouth or genitals.

It's essential to seek guidance from medical professionals for accurate diagnosis and appropriate management tailored to individual circumstances. Remember that maintaining open communication with your healthcare provider about any concerns regarding potential symptoms will help in determining proper care moving forward.
