Blood Safety and Testing ABC Members Collect and Test 7.5 Million Blood Units in 2003 The blood supply is the safest it's ever been. Thirteen tests – 11 for infectious diseases – are performed on each unit of donated blood. A strict screening process also helps ensure the safety of blood. Donating blood is 100 percent safe.

Donors may be temporarily or indefinitely deferred from donating blood, depending on the type of positive test result. In a few cases, the donor does not need to be deferred. The blood donation is almost always discarded. The donor is notified of any abnormal test results, or may be notified that their blood center wishes to consult personally with him/her. At that time, the blood center is able to help the donor understand the test result and subsequent deferral. Copyright © 1999 - 2008, America's Blood Centers.
