Twenty six days is not very long to obtain an accurate test. However, because your encounter did not involve intercourse, your only risk was oral sex – was he the giver to you or you to him or both? HSV 2 does not like the mouth. Do you know if he was on daily therapy or not? His index value is in the low positive range and there is a 50-50 chance that his test was a false positive. If that is the only way he was diagnosed with herpes, I would strongly recommend that he obtain a herpes western blot to clarify his diagnosis and, in turn, perhaps relieve your mind. by 6 weeks post exposure, the antibody test picks up about 70% of those infected with HSV 2. But again, your risk is very very minimal indeed.
