Blood Type Compatibility
Check blood type compatibility for donations and transfusions. See who can donate to and receive from your blood type.
Blood Type Compatibility Chart
Understanding blood type compatibility is essential for safe blood transfusions. Your blood type determines which antigens are on your red blood cells and which antibodies are in your plasma.
Key Facts
- Type O- is the universal donor (can give to anyone)
- Type AB+ is the universal recipient (can receive from anyone)
- Rh-positive types can receive from both Rh+ and Rh- donors
- Rh-negative types can only receive from Rh- donors
Frequently Asked Questions
What is the universal donor blood type?
O-negative (O-) is the universal donor because it has no A, B, or Rh antigens.
What is the universal recipient?
AB-positive (AB+) is the universal recipient because it has no antibodies against A, B, or Rh antigens.
Why does Rh factor matter?
The Rh factor (D antigen) determines whether blood is Rh-positive or Rh-negative. Rh-negative individuals can only safely receive Rh-negative blood.
