HSV 2 Antibodies Present, But Negative...How?

[nycot]

I've been tested 3 times for HSV 2 using the IGG test and these were the results:

Nov 2011: 0.93
Jan 2013: 1.23
April 2013: .06

I came up barely positive in January 2013, but negative/equivocal the other times. I will gladly accept that I am negative for HSV 2, but WHY do I have antibodies for the virus if I supposedly don't have it? To have antibodies would mean there had to have been a trigger, right?

Thanks for the response, Grace. Do you know why testing positive for HSV 1 can result in a false positive for HSV 2?

we know that having hsv1 is a factor in the false positives on hsv2 testing. probably other factors but we can't pinpoint them at this point.
