Hello, I had a risky contact with a csw in Africa. After 2 weeks I got shingles. After 67 days (approx. 10 weeks) I had myself tested in the laboratory with the Duo HIV Test. The test was negative. I am afraid of HIV 2. is the test safe against HIV2? is it true that antibody formation in HIV 2 takes longer? longer than 10 weeks? should I get tested again after 12 weeks? thanks
