It is unlikely you have HSV-2 at all. You can use the search link to find many discussions on this forum about interpreting the HSV-2 antibody testa. For a recent example of a case similar to yours, see this thread:
http://www.medhelp.org/posts/show/581379. (As you will see, it sorted out for that person exactly as I predict it will work out for you.)
The main point is that although the official recommendation from the test producer is that any ELISA ratio over 1.1 is positive, more recent research shows that only levels of 3.5 and higher are reliably positive. The higher the value toward 3.5, the more likely an accurate result. Only about 10-20% of people with values around 1.5 are actually infected. When that fact is combined with your obvious low risk for genital herpes, it is unlikely that your result is truly positive. It is not exactly true that low positive levels suggest early infection. That's a possibility, but it is more likely it's just a false positive result. Even if your result turns out to be truly positive, it is still more likely you have a longstanding infection, not a new one. The only wrinkle in your case is the genital pimple, which could be consistent with herpes. But most pimples and most herpes lesions really don't look the same to a trained provider, and your doctor's reassurance about the lesion probably was correct.
As you can find in other threads, this can be sorted out with repeat testing. One option is to ask your doctor to do a BiokitUSA HSV-2 blood test (which is performed in the office in 20 minutes). Even if your doc doesn't routinely provide the test, he can order a test kit from a local supplier and then test you. Research has demonstrated that the Biokit test is an excellent tie-breaker for low-positive results like yours.
Alternatively, you could ask your doctor to send blood for an HSV Western blot test, which is done at the University of Washington laboratory in Seattle (where the WB was developed and much of the research on HSV blood tets). It costs more than Biokit (perhaps $200 or more) and might not be covered by insurance, but WB is the gold standard in sorting out uncertain situations like this.
I hope this helps. When all is said and done, most likely you will find you don't have HSV-2, so don't be too worried as you wait for repeat test results.
Good luck-- HHH, MD
