i have very brief (<5sec) unprotected receptive anal encounter with a man of unknown status (I am male). Basically, he penetrated me without me being aware. Right after I realized I panicked and ran. After few weeks i had some symptoms e.g. temperature ~37.3C - 37.6C for like 10 days. A bit swollen lymph nodes (which might have been a result of constant touching it and double checking). I went for testing - Insti Hiv-1/Hiv-2 Antibody test and it was negative after 29 days after encounter.
I keep reading a lot about ability of Inti test to detect early HIV. One fact which makes me nervous is that even latest Insti test are being considered 2nd generation which would mean that I need to wait at least 42 days to get some reliable results.
On the other hand, I read few scientific studies saying that INSTI HIV-1/HIV-2 Antibody Test is highly sensitive and CAN detect also IgM antibodies which should allow detection of HIV, on average, after 22 days.
Any ideas or thoughts on accuracy of negative INSTI HIV-1/HIV-2 Antibody Test after 29 days?
Thank you so much! Really appreciate your help.
