Gay blood donations ban likely to be lifted?

[cloud999]

I thought they had to wait until after the undetectable window for HIV and THEN test the blood before they used it for a transfusion anyway.:confused:

Blood expires quickly...it lasts for just 15-42 days after donation, depending on the preservative used. The window period for routine HIV screening is currently 60 days...so even the best-preserved blood will expire long before the HIV window closes.

Hence, why donation centers go to great lengths to exclude people who are at high risk for undiagnosed HIV infections.
