Blood type tests are done before a person gets a blood transfusion and to check a pregnant woman's blood type. The following table shows the compatibility of blood types between blood donors and recipients.
Read the table as follows: A person who has A-negative blood can receive A-negative or O-negative blood.
| A person who has: | Can receive: |
|---|---|
A- blood | A-, O- blood |
A+ blood | A-, A+, O-, O+ blood |
B- blood | B-, O- blood |
B+ blood | B-, B+, O-, O+ blood |
AB- blood | AB-, O- blood |
AB+ blood | AB-, AB+, A-, A+, B-, B+, O-, O+ blood |
O- blood | O- blood |
O+ blood | O-, O+ blood |
Minor antigens (other than A, B, and Rh) on the red blood cells are also checked for a match before a blood transfusion.
