I took igg herpes test from quest 2 weeks ago. i had an index of 1.16. since then im on valtrek for 2 days. i retested today at my local immediate care and had results come back on igg with .20 which test do i trust? would valtrek lower my results?

Although HSV IgG results 1.1 and higher technically are positive, in fact most such results are mistaken. It's only when the value is 3.5 or higher that HSV2 is confirmed. In other words, your first result really didn't mean you have HSV2. Smart move having the second test: it proves you don't have it. (Herpes and STD experts would not have treated you based only on that first test result.)
