This is a very bad idea.
The test is not accurate, and even if it was, so what? Having antibodies to a retrovirus doesn't mean a damn thing.
All this is going to do is scare people into taking the test, then scare them into taking antiviral drugs, that will eventually kill them.
If you knew you had antibodies against measles, would you be worried about getting measles?
Don't get sucked into this whole idea that HIV = AIDS = DEATH...
Its all BS.
