Answer:
The importance of grouping
The grouping is very important when it comes to having a blood transfusion. If blood is given to a patient that has a blood type that is incompatible with the blood type of the blood that the patient receives, it can cause intravenous clumping in the patient’s blood which can be fatal. The patient’s body can start producing antibodies that attack the antigens on the blood cells in the blood that was given to the patient. For example, a patient who is blood group B has naturally occurring Anti-A antibodies in the blood. If this (blood group B) patient receives blood group A blood, the Anti-A antibodies in the blood of the patient will cause the blood group A blood cells to clump intravenously which is life threatening. Similarly, a patient who is blood group A has naturally occurring Anti-B antibodies in the blood. If this (blood group A) patient receives blood group B blood, the Anti-B antibodies in the blood of the patient will cause the blood group B blood cells to clump intravenously which is life threatening. Blood group O can be given safely to any other blood group is there are no naturally occurring antibodies in the blood of someone who is blood group O. Considering that a person can be either blood group A, B, AB or O and is either blood group RhD positive (also denoted as +) or RhD negative (also denoted as -), this means that a person can be one of eight blood groups: A+ (A RhD positive), A- (A RhD negative), B+, B-, AB+, AB-, O+, O-. The rarest blood groups amongst the population that donate blood in the UK are AB-, whereas the most common are O+. People who are blood group RhD positive, can be given either RhD positive or RhD negative blood, but people with RhD negative blood can only receive RhD negative blood.
