I don’t know what you mean by titer/IFA. Are you talking about the IgM here? The IgM is a terrible test, in my opinion. When this happens, people get a positive IgM and a negative IgG and down the road the IgG is still negative, it is almost impossible to get some people to believe that the IgM was just plain wrong. In your case, you have waiting more than enough time to test positive by IgG if you were going to. We advise waiting 3-4 months for accurate IgG testing – you have waited 7, right? I think you should show your doctor the CDC STD treatment guidelines that direct clinicians not to use IgM tests.
The traditional blood screening test misses 2-3 infections out of 100.
If you want to know if your cold sores are HSV 1 or 2, have a PCR swab done of the outbreak to be sure. You can also get a herpes western blot, the gold standard test, if you really want to be sure.
