The Tridot test detects both HIV-1 and HIV-2. I'm not sure where you read otherwise, but it's not true.
You have tested conclusively negative and do not need any additional testing. You do not have HIV.
Diver58, Anxious No more And Mike ur comments please
CurfewX has already provided you with the information that you needed to know. Your test specifically looks for antibodies to HIV 1 & 2, Group 'M' for "major", is a common type of HIV, with more than 90% of HIV infections responsible due to HIV-1 group M, the subtype E is a part of the above mentioned group.
The problem here is that you have read too much about HIV online, you have not been able to accept your result, testing out at 10 months and asking for advice on it's accuracy?
Please see a therapist for your anxiety, none of us here can tell you any thing that can lead you to believe that you don't have HIV. Only a therapist can help you with your guilt.
I second CurfewX and Mike_No. Their replies are comprehensive. Trust your test report and move on with your life normally. You do not have HIV.
Possibility of HIV transmission from a single, isolated act of unprotected sex ( or condom failure) is not as significant as you are imagining. The most significant odd in your favor is, her unknown status...... She was not a confirmed HIV+ and therefore there is a very strong possibility that she might not have the infection. This possibility drop your risk factor drastically because nobody can give something she/he does not have.
