You need to know blood types for you, your family, and all the other members of your group. You also need to know what types of blood you can receive and to whom you can donate.

A+ can receive A+, A-, O+,O- can donate to A+, AB+
A- can receive A-, O- can donate to A+, A-, AB+, AB-

B+ can receive B+, B-, O+, O- can donate to B+, AB+
B- can receive B-, O- can donate to B+, B-, AB+, AB-

AB+can receive everything--universal acceptor can donate only to AB+
AB- can receive A-, B-, AB-, O- can donate to AB+, AB-

O+ can receive O+, O- can donate to A+, B+, AB+, O+
O- can receive only O- can donate to everyone--universal donor

Because O- people can donate to anyone, they are called universal donors, or in more colorful language, walking blood banks. If you have one of these people in your group, and only one set of body armor, this person gets it.
