the 8 and half months Herpeselect Elisa test result was  HSV1 IgG postive， HSV2 IgG negative；
but I have take the blood test again in the 9 and half months, and the test was the TRINITY CAPTIA test, the result was the HSV2 IgG was postive, how to explian that?

Just bumping this for Grace as I am curious about the question as I thought the HerpeSelect was quite accurate.
