Understanding Blood Groups & Compatibility
August 5, 2026
A simple guide to which blood groups can donate to and receive from each other.
Blood compatibility saves lives. Here is the quick map:
- O-negative is the universal donor.
- AB-positive is the universal recipient.
- O+ can donate to any Rh-positive group.
- A and B can receive from O and their own type.
Always confirm with a lab cross-match before transfusion.
