1) Yes
2) We don’t know why some people get false positives. Also, it is possible that you have HSV 1 infection and it is simply not showing up in the screening ELISA because the test misses 1-2 out of 10 HSV 1 infections.
3) Likely not
4) That is no possible for me to know without knowing many other things about you, like your age, your race, your ethnicity, the age, race and ethnicity of all of your partner. And honestly, even if you gave me all of that, I am not willing to take the time to review all of the literature and make some statistical calculation. My math isn’t that good and it would take hours and hours of time.
5) no
If you question your antibody test results, I would strongly encourage you to get a herpes western blot antibody test. It is more sensitive for HSV 1. I think you can be comfortable that you don’t have HSV 2, but the western blot looks for both
After the time has passed since your negative results, you are still thinking about this, and I think maybe the western blot would help you feel more reassured.
