How unfortunate that your doctor chose to do an IgM antibody test – it is a really poor test with many many false positives – we see it ALL THE TIME! The likelihood that you got HSV 2 by giving one minute of oral sex is slim to none – really. The numbers have not changed in any significant way at all. Those are completely normal variations and tiny at that. I’ve seen WAY bigger variations – your numbers are in the very low range and I would bet money they will stay that way. Unfortunately, you are now burdened with this horrible IgM test result and probably won’t rest until you retest – that should be done at 12 weeks. You should point out to your doctor that the CDC in it’s 2015 STD Treatment Guidelines recommend against going the IgM test, in the herpes section. You should find it, copy it and send it to him/her in the mail. Perhaps they won’t make the mistake of doing this test with another poor patient.
