Your statistics are correct. According to the package insert, the Herpeselect picks up 97% of those infected with HSV 2 by 4 months. We don’t know for sure exactly how accurate the western blot is, no, in terms of how many actual infected people it picks up. We just know that it is better than any other antibody test for herpes.
I have had 9 patients in 32 years of practice that were swab test positive for HSV 2 and western blot negative.
