So I just tested positive for herpes type2, my igg index was 1.51 I was tested in june,2018 and also in February of this year both came back negative for type2. I have been positive for type 1 for years now. I have had two partners in the last four months,My Doctor said theres no way it’s a false diagnosis I have no symptoms what so ever. So my question is my last time with someone was May 12th would I need to give it more time and have another test? And if I was negative before could this really be a true positive? Also if I was wanting a western blot how long do I need to wait after exposure? And would my body already have antibodies at less than a month from possible exposure?thank you so much

You need a Western blot. You should wait three months from her last sexual encounter to do this test. You can work with your own provider to obtain this test from the University of Washington or you could work with me by doing a video conference which you can set up on the homepage of this website. There is an 85% chance that this is a false positive

Should I take another igg test to see if my levels go up before I take the western blot?
Also if I was to start meds now would that mess up the western blot test?
Should I not have any type of sexual contact until I get the western blot?
Is it possible to have two negative igg test then a low positive and it be false?

You could do another IgG test and if it way up, forget the blot. More than 2 weeks of antiviral therapy can impact testing but less, probably not.
I think if you have sex with anyone, you should disclose your current status but if protected by condoms, I don’t think it would change the timing of your test.
It is possible to get a false negative on the IgG test, yes. and then a false positive. All those things are possible with the IgG test.

Updated it’s been past 12 weeks from exposure I had another igg test done this time the number came back at 2.80 I do have colder soars and that number was at 36 so really high. With my other igg test being negative in june 2018 and in February 2019 would I even have a chance of a false positive? And if in fact it is false why would the index go up?
So in june 2018 negative
February 2019 negative
End of may 2019 igg 1.51
June 13 igg 1.41
I have had no outbreaks or anything, in this time frame I have unprotected sex with two men. Would a blot test be worth it at this point?

I paid for more questions I hope you see the one above this one as well. If I take the western blot what is my % that it could be a false positive? Also if I’m one of the people that don’t have an outbreak does that lesson the chance of me giving it to someone? And do you know the transmission rate with no condoms or meds?

With an index value of 2.8, you are still in the low positive range and a confirmatory test is still definitely recommended. The western blot has no false positives. Do you mean what is the likelihood with a 2.8 what is possibility of a false positive? I would say around 30-40%.
People who don’t have outbreaks but are indeed infected shed about half as much as those who do have outbreaks. The transmission rate from females to males with no condoms or meds is around 4% per year having sex twice a week.
