Guess it is true what they say " You can find an expert who will say what you want."
The doctor who said this is mis-informed. It is actually funny that you brought it up. Tonight I was out with a few friends and while we were drinking a cold one (well they drank I couldn't because I like being the DD) one of our friends friend is actually a doctor and my friend is a PA. We got to talking about Herpes after one of my friends shared his mixed drink with another and the Dr. said "I hope you don't have herpes." to which my comment was "wouldn't matter much since most of transmissions as an adult are from kissing not drink sharing. The alochol content would be enough to kill the virus anyway and the tempature as well of the class with ice would kill it too." We happened to discuss testing. (work with me here.)
Now the Dr is a cool guy and one of those who feels he is always learning. Just because he is an MD he never once has rubbed it into anyones face unless he is 100% sure on things. So he and I started talking about IgM and IgG blood tests.
I happened to show him the following post (which is what is in my journal).

Now this explains the testing and why IgM isn't going to the best for HSV earlier than other tests or that if it does only usually seen in children. I would enjoy for you to read Dr. Hansfield response. The Dr. Friend of a friend was rather interested and even reviewed Dr. Hansfields credintials.
The long and skinney is there is no reason for him to not test. Would be really easy to settle a few things and that is the IgG testing will only be good after 3 months of your last sexual encounter. My advice is have him get an IgG test and not the IgM.
