Big difference in HSV-2 score in two weeks. Answers?

I've been dating a guy for 1 month and we have not been intimate.  Before we do, I've asked him to get tested.  I have had a test since my last partner and am clear.  His last partner was in Oct. 2011 (protected sex) and one time.  He has ha no reason to suspect anything (no symptoms).  He has had one test last wk which the dr told him was positive. So he has already checked with the last partner and she said she had a test in Dec and is negative.

He had another test yesterday to double check (Elisa) and his results were .909 HSV-1, 1.071 HSV-2.  This was considered inconclusive.  So he went back to get the values from the initial dr.  Test was HerpesSelect.  He received .97 HSV-1, 3.71 HSV-2. IGM tested positive on EIA but negative on IFA.

This seems confusing. I have recommended a specialist. He has never had symptoms or reason to think he has HSV.  Any thoughts?
