HIV test accuracy

I got HIV Tested, twice. One was the finger prick test, the other was a 4th generation blood test (about 2 weeks later). Both were negative.

First test (finger prick): taken atleast 40 days after possible exposure. Negative .

Second Test (HIV 1/2 ANTIGEN/ANTIBODY, FOURTH GENERATION) atleast 50 days after possible exposure. Negative.

Are these conclusive? What’s the accuracy?

I don’t need any rude comments because anxiety is real. Yes I know I should visit the doctor again, I also want to help others, too. If you don’t have anything informative to say, please go on with your life❤️
