Over 100 years ago, it was discovered that people have different types of blood. The major types are O, A, B and AB. For a blood donation to be helpful to a patient, there has to be an appropriate match between the blood type of the donor and that of therecipient. Some types happily mix, while others do not. The common Type O can be safely transfused to patients with O, A, B or AB blood, but Type O patients can only receive blood from other Type O people. Each major blood group is divided into Rh negative or positive types. On average, 45% of the population is Type O, 40% Type A, 10% Type B, and 5% Type AB. Check the chart to see where you fit in.
