What blood type can receive blood from any donor?

  1. O+

  2. A-

  3. AB+

  4. B-

The correct answer is: AB+

The correct answer indicates that individuals with AB+ blood type are universal recipients, meaning they can receive blood from any donor without the risk of severe transfusion reactions. This is due to the presence of both A and B antigens on the surface of their red blood cells, as well as the absence of anti-A and anti-B antibodies in their plasma. Therefore, they do not have immune responses against A, B, or Rh factor antigens, which allows them to accept blood from all other types. In contrast, other blood types have specific antibodies that could react against antigens present in the transfused blood. For example, O+ lacks A and B antigens but possesses anti-A and anti-B antibodies, making it unable to receive blood from A, B, or AB types. A- has A antigens but also carries anti-B antibodies, limiting compatibility to A- and O- blood. B- possesses B antigens and anti-A antibodies, which restricts acceptance of A blood types as well. Therefore, the AB+ individuals have the broadest compatibility for blood transfusions.
