I’m concerned that you said you contacted your doctor and set up a western blot. That is generally not possible. Are you absolutely certain it is a herpes western blot going to the University of Washington? Please double check. I a concerned that he may have ordered something else. The western blot is not normally available through your doctor’s office. Please double check.
Yes, commonly false positives are due to cross reactivity between HSV 1 and HSV 2.
