Hi!fingering incident. hiv duo test result at 5th week (non reactive 0.1), at 7th week ( non reactive 0.62) is conclusive? increased value is concern?

No worries: First, fingering or other hand-genital contact his risk free for HIV. There has never been a reported case. Second, a duo test at 5 weeks is about 99% conclusive. Finally, the variable numerical result is meaningless. All values under the cutoff (usually 0.9) are equally negative. (The same specimen tested 10 times would give 10 different members.) Move on without worry and no more HIV tests.
