Universal blood recipient blood group has which antigen and which antibodies respectively?

CONCEPT:

Universal Blood Recipient Blood Group

• The universal blood recipient blood group is AB.
• Blood groups are classified based on the presence or absence of antigens (A and B) on the surface of red blood cells and antibodies (anti-A and anti-B) in the plasma.
• The AB blood group contains both Antigen A and Antigen B on the surface of red blood cells.
• It does not have anti-A or anti-B antibodies in the plasma, allowing individuals with this blood group to receive blood from all other blood groups safely.

EXPLANATION:

• Blood compatibility is determined by antigens present on red blood cells and antibodies in the plasma.
• Individuals with blood group AB:
  • Have both Antigen A and Antigen B on the surface of their red blood cells.
  • Do not produce anti-A or anti-B antibodies in their plasma.
• Since they lack these antibodies, their immune system does not attack blood from other groups (A, B, AB, or O).

Thus, AB blood group individuals are known as universal recipients, as they can receive blood from all other groups without any adverse immune reaction.

Therefore, the universal blood recipient blood group has Antigen A and B, and no antibodies.
