Humans have 8 blood types:
A+ and A-
B+ and B-
AB+ and AB-
O+ and O-
all types can receive donations from their individual blood type (for example anyone with A+ can receive and donate to other A+ members) in addition, anyone with A+, A-, B+, and B- can donate to anyone who has AB+ or AB-.
O- can receive all types and AB+ can donate to all types
There are four blood types, O, A, AB and B. In addition, each of these types can be negative or positive. This designation denotes whether the blood is Rh positive or negative. A positive blood type cannot donate to a negative blood type. Such a donation could cause a serious, life threatening reaction.
There are currently eight blood types which include: O+, A+, B+, AB+, O-, A-, B-, and AB-. O positive is currently the most found in the world and AB- is the rarest found with only .5% of the world with that type of blood.
There are only four bloodtypes. There is bloodtype A and bloodtype B. Then there is bloodtype AB which is compatible with both blood types A and B. Finally, there is bloodtype O which is only compatible with its own bloodtype.
