I think you do NOT have HSV 2. Your blood tests are very consistent and the ELISA test for HSV 2 is quite good – picks up 97 out of 100 cases when you wait long enough to be tested from a concerning sexual encounter. 15 weeks is reliable. Your fungal infections sound like just that – fungal infections, not unusual with all the antibiotics you have taken.
As for HSV 1, do we even know that is a risk? Have you been tested previously for HSV 1? Have you ever in your life had a cold sore
I don’t recommend any more antibody testing at this point. Wait until we talk a bit more.
