Best Answer

Yes. Before they take your blood, they will do a fingerprick test to see if you have enough iron in your blood. If you are anaemic, they won't take your blood. After they have taken your donation of blood, it is put through several tests in the laboratory before the blood is used. The lab tests will check for Infectious Diseases that could infect the person receiving the donated blood.
