Blood Type Compatibility

Blood Type Compatibility

Part of what makes blood so fascinating is that only certain blood types are compatible to be transfused to patients with other blood types. Blood types are determined by a person’s genetics and vary widely from country to country. Have you heard of the universal donor? The blood type of a universal donor is O negative, and only about 9% of the population has this blood type. The most common blood type is O positive, with 39% of the population having this blood type. The next most common, with 31% of the population, is A positive.

So, which blood types are compatible with yours? Which blood types could you potentially receive if you ever needed a blood transfusion? This chart will help to answer those exact questions.
