I had hsv 1 igg and igm test it was 0.50 also hsv 2 igg and igm which was also 0.50 values under 0.90 are negative.I had classic oral hsv symtoms 2 weeks after a potential exposure in December 2015. I got tested one month back it was not western blot.i strongly feel my report is false negative is it possible to get a false negative blood test report for hsv 1&2 for both igg and igm should I go for a western blot test.
