My herpeSelect Elisa IgG score is 3.3. Could it be false positive?

Hello doctor,

I met with a girl a few months back. She had been rubbing her vagina and then put her finger in my backside. She said she was clean but hard to know. After about three months, I got tested for STD (Sexually Transmitted Disease) panel and came up negative with everything including (Herpes Simplex Virus) HSV 2 except for HSV 1, which came up positive. However, the test used was herpes Select Elisa (Enzyme Linked Immunosorbent Assay) IgG (Immunoglobulin G), which I read is known to have false positives. My score was 3.3. I read if the score is less than 3.5 then it could be a false positive. A week later, I retested using herpes Select immunoblot, which is supposed to be more accurate and tested negative for HSV 1 and 2. However, for the past three months, I am having itching in my backside, which could be due to sweat and anxiety. Do I have anything to worry about or trust the latest results that I have no herpes and put this to rest?
