Good indication. However, you can test at 28 days with a duo for a conclusive.
My apologies for reading incorrectly, I was almost half asleep in the morning.
At 7 weeks, you don't need an RNA PCR, a simple standard antibody test can rule out HIV infection as suggested by CurfewX.
You can just take any lab based antibody test to follow the recommended testing at this point. Although, absence of HIV-1 &2 RNA in your assay only means that you don't have HIV. Just finish the formality, collect your antibody negative.
