Question : HI I have a question, I have tested 33 days after exposure. Tests I took included : HIV DNA, PCR/HIV Ab, HIV-DNA by PCR, HIV-DNA RT by PCR , HIV 1/0/2 Abs-Index Value <1.00 , HIV 1/0/2 Abs, Qual Non Reactive on both. HIV-1 DNA NOT DETECTED. Done by LabCorp.

My stress level is just sky high. Thank you for your answere in advance.

Hello JekaAcnrep,
Thanks for your query.
You have undergone a complete battery of tests and they indicate that you are not infected. 33 days is a good enough period for the infection to be detected through these tests. Please check if a p24 antigen analysis has been done or not as it is one of the first viral antigens to be detected through PCR.
I do not see any point in getting yourself undergo this exhaustive battery again. You may consider getting an HIV ELISA done at this stage ( it is a quick and cheap test). Just to be doubly sure. Just relax and be careful in the future. I hope I have answered your query. I shall be available if you have any further queries.
Thanks
