What was your risky exposure?
There is some debate about herpes testing. I think if after 2 years you haven't had any symptoms, you don't really need to test, and I say that because there are a pretty decent numbers of false positives on the hsv2 blood test, and unraveling that can take months and several hundred dollars, not to mention the anxiety it causes.
If you tell me more about your exposure, I can offer more advice about whether you even need to test.
