People have different blood types, which are also known as blood groups. There are several blood types—A, B, O and combination. Type O is considered the universal blood type.
It is important for a person to know his blood type for medical reasons. Should one needs blood transfusion, it is critical that he gets blood donation of the same or compatible blood type.
The Blood Type Calculator is a helpful tool to determine paternity of a child. It allows you to determine the possible blood type of your baby especially if the parents have different blood groups. Although the results may not be conclusive, it is still a fun tool to find out what your child’s blood type could be.
