I am an inhabitant of a country where it seems that medical tests worn out by time are more popular. I have been to several clinics and hospitals, and all of them offer Elisa combined tests for HSV I and II for igg and igm antibodies. While I know igm tests are useless, my question is related to the igg factor.
About a year ago I was involved in unprotected sex with a partner whom I had known for a while and trusted completely. We broke up and then I waited three months to get tested because I had learnt that igg antibodies take time to develop. When I tested after three months, the combined result for HSV I and II igg value was 0.35 which is clearly negative.
I have not been involved sexually ever since, and then for safety's sake I got re-tested in December (which would be about 13 months since last sexual encounter). This time I did the test in another clinic and the value for igg antibodies for combined HSV I and II came out as 0.74
While the result is still negative, I am worried about the increase in the value. Most of the forums here state that a value under 0.90 would mean there is no herpes infection, still I would like to know why there has been an increase in the igg level? Does this mean there is a verrrry slow seroconversion happening (which is still not positive even a year after sexual activity) or is it a given fact that every time the same subject gets tested and is negative for herpes, the index value could still be anything between 0.1 to 0.8?
Basically put- Can I safely assume I have no HSV infection, or do I take a test again three months later to be sure?
I would be really happy if I obtained some information on this. Thanks!
