Understanding Blood Type Compatibility

1. Blood Type Basics: Blood types are determined by the presence or absence of specific antigens (A and B) on the surface of red blood cells. For blood donation, compatibility depends on these antigens.

2. Type A Blood: Individuals with type A blood have A antigens and produce anti-B antibodies. Therefore, they can donate blood to those who do not have B antigens.

Compatibility Analysis

3. Donor Compatibility:
   • Type A: Can receive from A and O types. Can donate to A and AB types.
   • Type B: Contains B antigens; cannot receive A blood (because of anti-A antibodies).
   • Type O: Universal donor but cannot give to AB.
   • Type AB: Universal recipient (receives from A, B, O, and AB).

Final Summary of Compatibility

• A person with type A blood can donate red blood cells to:
  • Type A (compatible)
  • Type AB (compatible)

Final Answer

Type A blood can be donated to Type A and Type AB recipients.
