My lab results from BioReference came back today with HSV-1 IgG at 0.02 but HSV-2 IgG at 0.31.   Both had a reference range of <0.90 as negative, so both showed up as negative.  However, is there is any significance to the HSV-2 being at 0.31 (vs. something much lower / closer to zero?).  Could it be that the titer is building and become >0.91 in a few days / weeks (e.g. if I'm in the window period)?  Or is this test result definitively negative?

Thanks, Terri.   The encounter was about 7-8 weeks before the blood draw for the test.   The question I have is specifically :  whether the 0.31 HSV-2 IgG test itself indicates any buildup of antibodies (as opposed to a read of zero or 0.0x).   I realize that the window period for a definitive IgG test is somewhat longer than the 7-8 weeks, and that I can't know for sure unless I retest another 4 - 8 weeks later, so I'm worried that it may be building the antibody levels and in a few more weeks could be >0.90 ?   Or is this not the right way to think of a read of 0.31? 

Terri or Dr Handsfield, any further thoughts here?
