I see you did renew with more questions. So if there is an 85% chance his test is a false positive then I’m confused as to why you believe that you have HSV 2 at this point. You had two years of sex and he was still negative in 2012, right? I do find it very difficult when an office nurse with no special expertise in herpes (that I know about), gives patients information like you have been given. He needs confirmatory testing and you need a type specific antibody test, definitely not an antigen test if you have no lesions.
You can look up this reference on PubMed (google it) and print it out to take to your appointment if you like and for your own information.
