Re: Urgent - post exposure prophylaxis for Herpes

Regarding false positives and negatives -- understand this is possible, but is it common? Or are we talking about a small and unlikely minority?

Reason being that in the activities which are related to this forum, I accept there is no such thing as zero risk, we are just aiming for reduced risk.

What I do remember reading is that there is cross-interference between HSV1 and HSV2. Meaning if your blood is positive for one, it could actually be the other.

However, I don't remember reading anything which says outright that if your blood test is negative for both HSV 1 and HSV2, you could still have one or both of them. I've done many HSV1 and 2 blood tests over the years, all negative and no doctor has mentioned the possibility of false negatives.

Thanks boss!

As for the Herpes blood tests I would not put too much faith in them as both false positive and negative results are possible.
