I don't know when or if I was exposed to HSV1 or 2, but two weeks ago I developed a lesion on my lower lip, right on the lip line. It didn't go through the classic cold sore stages, but after a week of it not going away I decided to see a doctor. My doctor didn't think it was a cold sore (said if it was that it wasn't active), but I requested the IgG type-specific antibody test to make sure. I got my results back today and they were very low negatives for both types (HSV1: 0.10, HSV2: 0.05). I have read on these forums that IgG test results cannot be confirmed for certain until four months after possible exposure.
Is it safe for me to assume that I have never been exposed to either type, or is it possible that I was tested one-week into a small outbreak and still had such low levels of antibodies? Thank you for your help.
