Blood Donation Compatibility
Understand which blood groups are compatible for donation and transfusion. This guide helps donors and recipients make informed decisions during emergencies.

|---|---|---|
A+ | A+AB+ | A+A-O+O- |
A- | A+A-AB+AB- | A-O- |
B+ | B+AB+ | B+B-O+O- |
B- | B+B-AB+AB- | B-O- |
AB+Universal Recipient | AB+ | A+A-B+B-AB+AB-O+O- |

O- (O Negative) is called the universal donor. O- blood can be transfused to patients of all blood groups in emergency situations when the recipient's blood type is unknown. This makes O- donors critically important for trauma and emergency medicine.
AB+ (AB Positive) is called the universal recipient. Individuals with AB+ blood can receive red blood cells from all blood groups, making them compatible with any donor. However, AB+ donors can only donate to other AB+ recipients.
- Rh Factor matters: Rh-negative patients should ideally receive Rh-negative blood to avoid sensitization. Rh-positive patients can receive both Rh-positive and Rh-negative blood.
- Plasma compatibility is reversed: For plasma transfusions, AB type is the universal plasma donor, and O type is the universal plasma recipient.
- Always verify with medical professionals: This chart is a general guide. Actual transfusion decisions should be made by qualified healthcare providers based on full cross-matching and patient-specific factors.
- In emergencies, O- is used: When there is no time to determine a patient's blood type, O- blood is the safest choice for emergency transfusions.
