Verified step by step guidance

Understand the concept of blood types: Blood types are determined by the presence or absence of specific antigens on the surface of red blood cells. The main antigens are A, B, and Rh factor (positive or negative).

Identify the universal recipient: The universal recipient is the blood type that can receive red blood cells from any other blood type without causing an immune reaction.

Consider the role of antigens and antibodies: A person with Type AB positive blood has both A and B antigens on their red blood cells and does not have anti-A or anti-B antibodies in their plasma. Additionally, the Rh factor is positive, meaning they can receive Rh-positive or Rh-negative blood.

Compare with other blood types: Type O negative is the universal donor, not the recipient, because it lacks A, B, and Rh antigens, minimizing the risk of an immune response when donated to others.

Conclude with the correct answer: Type AB positive is considered the universal recipient because it can accept red blood cells from any blood type without the risk of an immune reaction due to the absence of anti-A, anti-B, and anti-Rh antibodies.
