This scenario should result in hiv transmission. Your test would detect 99% of hiv infections when performed in 6 weeks. If done before that a confirmatory test is needed at 3 months. Your public health department can also advise you.

I believe there's a typo in in Dr. C's reply: "This scenario should NOT result in HIV transmission."

This was a zero-risk exposure for HIV and other STDs. You didn't need HIV testing at all. But this result is around 95% conclusive. You could have another at 6 weeks for a conclusive result, but there's really no need.
