I should have said though, that if you had a true HIV exposure, then you need to test out at three months to really be sure you are negative. If you have not had a true exposure but are suffering from HIV anxiety, then you didn't need to test to begin with and you can take this negative test and run with it.
If you are infected with HIV, your body would produce antibodies to the infection. It looks like they are saying no antibodies were detected with both tests therefore you are testing negative for HIV.
