HIV antigen on blood rapid test kit

Hi Doctors,

Several questions on HIV blood rapid test kits.

I have purchased a hiv blood rapid test kit and carried out test at home. As I read the instruction on the kit, I know that on the blood collecting sample area on the kit, there is HIV virus antigen, which will react with the HIV antibody in finger blood (if exist) to further process.

Q1. Are the rapid test result taken on 90 days post exposure conclusive?
Q2. If my bloody finger with wound (cut) touch the sample area (with antigen) of the test kit, will I be infected by the HIV virus?
Q3. What is the HIV antigen used on the sample zone on the test kit, are they virus?

Thanks a lot!

The above questions are exactly why there are no approved home testing kits.
