How definitive is the IgG blood test?
My doctor said it's not definitive/conclusive, but I tested negative for HSV2 IgG (result didn't specify the indication level) 8+ weeks after initial diagnosis, 10+ weeks after possible initial exposure and was wondering what conclusions to actually draw.
Reading http://www.biokitusa.com/NCCLS_BK_HSV-2_Whole_Bood.pdf it seems like it's in the 85%-95% ranges, but I'm not fully clear on how to interpret sensitivity and specificity (I guess I should look at the sensitivity since I'm concerned about a false negative).
Background: Had unprotected sex w girlfriend, 2 weeks later got what looked like zits on my shaft underneath the foreskin, went to the doctor, doctor says it's herpes but the presumed vescicles don't really have any liquid in them, nor do they ulcerate and crust (and the virus culture came back negative, as the doc said to expect).
About two months later I go back for a blood test, which comes back negative, but the doc says it's not conclusive - "it'll tell you if you have it, but won't tell you if you don't" kind of thing.
I haven't had any more outbreaks, but I'm obviously concerned about my health and what to tell future partners.
Is there any other test I should have done to get a conclusive diagnosis?
