If it's already been a couple of months ((over 2 or 3 months)) after your last sex with your boyfriend, then you would have antibodies for sure. That is why the antibody portion of the test trumps anything else. However, since there is a reactive result, it is just logical to get tested again. Try to keep calm and expect a negative on your next test.
When was your last exposure by the way ?
I missed something. If you were negative for antibodies on a second test, and it has already been 3 months post your last exposure, why does your doctor want a third test ?
Please bear in mind that the RNA is quite expensive, and if a second test was negative for antibodies ((in the right time frame)), then it should have been regarded as your confirmatory result.
Please ask your doctor about this.
I'm sorry, my internet is a bit slow today. I just saw your second comment.
The guidelines are 12 weeks, but an 8 week negative has never been seen to turn positive later on.
If I were you, I would just get another antibody test at 12 weeks to fulfill the guidelines and put this behind me.
Anyway, the important thing is that you are "almost 100%" negative, and any action you take from here on would just be a confirmation of that. But again, since it isn't 3 months yet, some sort of confirmation test is still required.
I'm sorry, my internet is a bit slow and so am I today.
Look, if you have doubts while being with ANYONE, then you should use protection. It's as simple as that. If you feel you've had a risk, the only sure way to know is an antibody test at 12 weeks post exposure.
As for the previous tests, the second one rules, but if you still have doubts about him ((due to any reason)) and are having unprotected sex with him again, then you have to try to make the right decisions.
