Diagnosed with HIV with instant test. How is it possible that I have had unprotected sex with him and he is negative ?

I have just been diagnosed with HIV yesterday (using the instant HIV test and one line is very dark and the other extremely light). Prior to yesterday, I have tested and came back negative. The last tests I did where last year April and October and both tests where negative. I started dating my boyfriend last year June and we hardly ever use protection. I have had an abortion done last year December and had a family planning injection this year January. The reason I need your expertise is because my boyfriend tested negative and I have ever since been with him. He still needs to test in May (after the window period) but in the mean time I need to make sure that I am positive or not. If I am, how is it possible that I have been having unprotected sex with him and he is negative.This is really tormenting me because I have been completely faithful to him and before that I was negative and used protection with the previous people I have been sexually active with.

Firstly, the instant test may not be completely relied upon. Get the standard ELISA testing done for HIV detection, in a standard laboratory.

Secondly, individual responses to the HIV tests vary depending on the viral load, the antibody titers in the blood, the specificity and the sensitivity of the test used.

Thirdly, let us talk only about you in this instance. You have been faithful to your boyfriend, and you have tested negative before that.

It is possible that your boyfriend has had a false negative test or that you have had a false positive test.

Whatever the concern, please get the HIV ELISA test done at a laboratory. Get your boyfriend re-tested as well.

You may go in for more confirmatory tests like Western blot or even NAAT or even P 24 antigen assays.

Wish you good luck.

Take care!
