Blood is grouped into four types: A, B, AB, and O.
Each type is also classified by an RH factor – either positive ( + ) or
negative ( - ). When a blood transfusion is necessary, donor and patient
blood must be compatible. If not, the patient’s body will react to the
incompatible donor cells, leading to complications, maybe even death.
Your ABO blood grouping and Rh factor are inherited
from your parents. Check the chart below to see what percentage of the
population shares your ABO grouping.
