Dry skin is not a symptom of herpes and I am not concerned about the dry white dust line that you are describing.
Some labs report out actual values of the IgG herpeselect, others just report out the <.90 which is what your lab did. Since the numbers really don't matter because they will vary according to the control that they are run against, I don't think you should be focused on those numbers, and you probably aren't going to get them anyway. You will just have to wait! Terri
