Question: Can A STD test mistake HSV 1 for 2?


 demolitionlover627 - Tue Feb 09, 2010 3:17 am

About a year ago, I had an STD test just to be sure I was clean of everything.
My blood test came back clear and they took a sample from my penis which also came back clear.

The doctor however told me that I had herpes. He couldn't however tell me which type, when I asked type 1 or 2? and turns out now I can see how inexperienced the doctor was.
I know I have a history of HSV1 because I have had cold sores on my mouth since I was a small child, and my mother had them, sister had them, so forth.

But I was curious if the STD test could have mistaken type 1 for 2 or if the virus is in your blood automatically because a patient has a history of type 1. What makes this even harder is the fact that he wouldn't specify the type.
I haven't had any outbreaks whatsoever in my genital region anywhere, but to this day I continue to get a cold sore about twice or more a year on my lip.

Thank you your answer is appreciated greatly.

User avatar Hello,There are specific tests and nonspecific tests for HSV.It all depends what tests were ordered.The ELISA test can not distinguish between type 1 and 2 and cross react.Viral cultures are done on active vesicles or blisters so do PCR testing which are specific.Since you have tested negative there should be no cause for concern.Best wishes.
