In the past few years (2-3 years) I got tested for Herpes and the levels were 2.8 IU/ml for IgM, but the doctor wasn't sure which type I have. I am pretty sure that I had type 1 since I had in my childhood cold sores in my mouth several times. My questions are, these levels are high?? and How can I be sure that I had type 1 or 2?
