Detailed explanation-1: -O positive red blood cells are not universally compatible to all types, but they are compatible to any red blood cells that are positive (A+, B+, O+, AB+). Over 80% of the population has a positive blood type and can receive O positive blood.

Detailed explanation-2: -Group O can donate red blood cells to anybody. It’s the universal donor.

Detailed explanation-3: -Type O-positive blood can be transfused to any positive blood type: A-positive, B-positive, AB-positive, and of course other O-positives. Patients with O-positive blood can receive blood transfusions from other O-positives or O-negative donors. The ideal donation types for O+ donors are whole blood or Power Red.

Detailed explanation-4: -Preferred donation methods: platelet and whole blood. Only types A and AB+ can receive type A+, but A+ platelets can go anywhere (except childbearing aged females of types O-, A-, B-and AB-). Type A+ can receive types A, O+ and O-. Only types A, O+ and O-can receive A+ plasma.
