Blood Group Chart | Blood Type Compatibility Table
A blood group chart helps understand which blood types are compatible for donation and transfusion. Knowing blood group compatibility is essential during emergencies, surgeries, and medical treatments to ensure safe blood transfusion.
Blood groups are classified based on the ABO system (A, B, AB, O) and the Rh factor (positive or negative). Together, they form the eight common blood types: A+, A-, B+, B-, AB+, AB-, O+, and O-.
Blood Group Compatibility Chart
| Blood Group | Can Donate To | Can Receive From |
|---|---|---|
| O- | All Blood Groups | O- |
| O+ | O+, A+, B+, AB+ | O+, O- |
| A- | A-, A+, AB-, AB+ | A-, O- |
| A+ | A+, AB+ | A+, A-, O+, O- |
| B- | B-, B+, AB-, AB+ | B-, O- |
| B+ | B+, AB+ | B+, B-, O+, O- |
| AB- | AB-, AB+ | AB-, A-, B-, O- |
| AB+ | AB+ | All Blood Groups |
Understanding Blood Group Compatibility
Blood compatibility depends on antigens present on red blood cells and antibodies in plasma. A mismatch can cause serious immune reactions, which is why proper blood matching is critical before transfusion.
- O Negative: Universal donor (can give to all)
- AB Positive: Universal receiver (can receive from all)
- Rh Factor: Positive or negative compatibility must be considered
