Low false positives are common. Hsv2 igg tests are very sensitive and pick up odd protiens and what not. Any number under 3.5 is suspect. With your protected exposures and this low a number it is almost certainly a false positive. Retest is a few weeks and see what happens. If that test comes back negative (which I believe it will) then move on without concern
I have been freaking out about my situations so I contacted a leading Dr in this field. He feels my lesions are not HSV and this is what is now the new recommendation pertaining to blood test. I will bet you have fallen into a false Poz. Good luck hope this helps.
"I will also urge you not to pursue this with a herpes blood test. As it happens, this very week, The Journal of The American Medical Association (JAMA) will publish official recommendations from the U.S. Preventative Services Task Force and an accompanying editorial that I wrote both recommending against blood tests for herpes in most people because of problems with test performance (questionable sensitivity, high rates of falsely positive results). In situations such as yours, unless the lesions occur at which time further evaluation is warranted, I recommend against the HSV blood test. If that happens, it would be far better to seek a HSV-PCR test than to pursue the diagnosis with a blood test".
