Actually even the WB isn't as accurate for hsv1 as it is hsv2.
Not true interesting1. People positive for HSV-1 can often still test negative with HerpesSelect, even after 1 year. It's not typical, but it's not unheard of.
Now, you could test again with WesterBlot, as after 1 year that will detect nearly all infections. That might be a good idea in this case. Or, you can test a PCR swab of the region during an "outbreak." That can detect herpes in the absence of antibodies. Then at least you could get your herpes typed.
if your blood test is negative after 1 year of exposure then you don’t have herpes, unless your immune system is not functioning accordingly!
Did you ever have your genital rash cultured for herpes?
If your blood tests are all negative - perhaps it's really not herpes ? What other sort of work up have you been thru?
Mouth ulcers are not herpes - they are canker sores which aren't contagious .
