You were never at risk of transmission. Below enlisted are the only HIV risks in adults:
1. Unprotected vaginal or anal intercourse
2. Sharing IV needles with people who inject drugs.
Your symptoms have nothing to do with HIV. Please consider seeing another doctor to find out the cause of your ailments and see a therapist to seek help in context to your anxiety.
You have no need whatsoever to get even an antibody test, forget about the PCRs - DNA / RNA, you don't need any of it.
Please move on.
Hiv 1 quantitative pcr - looks for the virus and measures the quantity of virus in the blood.
The result of this test would be in copies/ml . if the person is hiv negative, the result would be 'not detected or undetectable'. This is generally done to monitor hiv patients but is also done for diagnosis
Hiv2 qualitative - it is similar to the above test. But it doesnt measure the amount of the virus. It just says if the virus is present or not.
The result would be DETECTED in case of positive for hiv2
Not detected in case of negative.
These tests are done for early detection of hiv generally.
You said you tested at 6 weeks? What were those tests?
You had no risk. This whole discussion about testing at 6 weeks and testing on a NAT is redundant as this is leading you nowhere.
See a therapist for your anxiety, this is what you are required to do from here.
