Most people have an inherited antigen on their red blood cells known as Rh, or D antigen. When the D antigen is present, a person’s blood is designated Rh positive. When D antigen is missing, the blood group is designated Rh negative. In general, Rh negative blood is given to Rh negative patients, and Rh positive blood or Rh negative blood may be given to Rh positive patients.

How is the blood supply protected from HIV?
The Red Cross protects the blood supply from HIV in the following ways:- The Red Cross educates donors about who should give blood by having every potential donor read the publication ‘What You Must Know Before Giving Blood’.
- Trained staff interview potential donors and review their medical histories.
- Donors have the opportunity to stop the donation process. After donating they can call to confidentially instruct the Red Cross not to use their blood for transfusion to patients.
- The Red Cross tests each donor’s blood donation every time he or she donates. Highly sensitive tests performed on samples from each blood donation are effective in detecting HIV exposure.
- All blood that tests positive for any infectious disease is destroyed.
