How is Blood Type Determined?

Blood types are determined on the basis of the presence or absence of certain antigens which can trigger an immune response in case they are foreign to the body. It is very important to find the RH or rhesus factor to determine whether or not the transfused blood will be appropriate. In case the blood is of a different type, the body may try to attack the foreign blood. This is precisely why blood types are important to know about in blood transfusions.

 Types of Blood:

There are four main types of blood which is determined heavily by the presence or absence of A or B antigens as well as antibodies within the plasma. The Rh factor determines whether or not there are antigens present within the blood. This makes up a total of eight blood types, namely; 0+, 0-, AB+, AB-, A+, A-, B+, and B-. Type O blood is the only blood group that does not have any A or B antigens within the plasma. O+ is the most common of all blood types and accounts for about 37% to 53% of people across difference ethnic and racial groups throughout the world.

People with the O blood group are universal donors because their blood does not contain any antigens. The absence of these antigens makes the blood usable for all kinds of blood groups because people’s bodies will not attack or reject the transfused blood. O- blood group is used in numerous hospitals where the patient is in a critical, life or death situations, and their blood group is unknown. Regardless of whether or not the blood type is known, type O- blood is particularly useful to transfuse to newborn babies who do not have a fully developed immune system.
