I'm trying to understand the difference between the Dengue IgG and IgM tests and the dengue NS1 test. When should one be used over the other? Are they looking for different things, and does it matter how soon after symptoms show up that you take them?

I'm just curious about how reliable the HIV rapid test is at the six-month mark, like after 180 days. Can you share if it's considered conclusive by then?

No it's not confirmatory, it's screening test, confirmatory test would be ELISA.

I'm really worried because I had unprotected oral sex with a commercial sex worker back in October 2020. Since then, Ive had persistent lymphadenopathy. I've taken numerous tests: HIV Tridot on December 6th came back negative, HIV ELISA on December 16th also negative. I had an HIV-1 RNA PCR test in the first week of January which was negative, and then HIV-2 RNA PCR and western blot on January 19th also negative. Even tests like the HIV duo on January 30th and western blot on February 10th were negative, and I did assessments at the 7-month mark including HIV duo, western blot, HIV qualitative RNA PCR, and ICTCall came back negative. Should I still be worried about HIV?
