There are 8 main blood types in humans, classified based on the ABO system and the presence or absence of the Rh factor. Here’s an overview of the types and donation compatibility:

Blood Types

1. A+

   • Can donate to: A+, AB+
   • Can receive from: A+, A-, O+, O-

2. A-

   • Can donate to: A+, A-, AB+, AB-
   • Can receive from: A-, O-

3. B+

   • Can donate to: B+, AB+
   • Can receive from: B+, B-, O+, O-

4. B-

   • Can donate to: B+, B-, AB+, AB-
   • Can receive from: B-, O-

5. AB+ (Universal recipient)

   • Can donate to: AB+
   • Can receive from: All blood types

6. AB-

   • Can donate to: AB+, AB-
   • Can receive from: AB-, A-, B-, O-

7. O+

   • Can donate to: O+, A+, B+, AB+
   • Can receive from: O+, O-

8. O- (Universal donor)

   • Can donate to: All blood types
   • Can receive from: O-

Key Points on Compatibility

• O- is the universal donor: It can be given to anyone because it lacks A, B, and Rh antigens, making it least likely to cause a reaction.
• AB+ is the universal recipient: People with AB+ blood can receive any blood type since they have all antigens (A, B, and Rh).

Why Compatibility Matters

Blood transfusions require compatibility to prevent immune reactions. Incompatible blood types can cause serious complications like hemolysis or organ failure.

If you are considering donating blood, consult local blood banks or healthcare providers for specific donation guidelines.
