That is the 3% that may take long that 3 months. You do not have an HIV concern.

In an adult, a positive HIV antibody test result means that the person is infected, a person with a negative or inconclusive result may be in the “window for 4 to 6 weeks but occasionally up to 3 months after HIV exposure. Persons at high risk who initially test negative should be retested 3 months after exposure to confirm results
No. How is that relevant? I am saying I had a high risk exposure how can I be sure I do not have HIV?
You on chemo, taking antirejection drugs or an organ transplant or an IV drug user that shares works with other drug users?
Then how do you explain the much less than 100% accuracy?
If you test negative anytime after 3 months post exposure, you do not have an HIV concern.
