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 patients blood which can be fatal. For any living organism to survive in this world they require proteins nutrients and oxygen.
The accurate grouping of blood is very important when it comes to having a blood transfusion.
Importance of blood grouping. The importance of blood grouping in transfusions. The accurate grouping of blood 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 patients blood which can be fatal.
Importance of the blood groups in laboratory and clinical medicine. N Engl J Med. The importance of the blood groups in legal medicine is obvious.
Besides the identification of persons the ability to determine that blood is not from a particular person is very important. Blood grouping and cross-matching is one of the few important tests that the anaesthesiologist orders during perioperative period. Hence a proper understanding of the blood group system their clinical significance typing and cross-matching tests and current perspective are of paramount importance to prevent transfusion-related complications.
Fascinatingly the normal function of ABO and Rh the two most important blood group systems is still essentially unknown. Blood group test is also important to regulate the blood type of a person. It is also crucial if one needs to go for blood transfusion or is donating blood.
This is because all the blood groups are not the same. It is therefore essential to know the blood group through blood group test. Thus a blood grouping test is very important for every individual to help know his blood group and Rh-type as it will be convenient for healthcare providers to provide medical care immediately in case of an emergency.
It is also useful to know your blood type if you wish to donate blood to a dear one in case of emergency.

The significance of the Rh blood group is related to the fact that the Rh antigens are highly immunogenic. In the case of the D antigen individuals who do not produce the D antigen will produce anti-D if they encounter the D antigen on transfused RBCs causing a hemolytic transfusion reaction HTR or on fetal RBCs causing HDN. The importance of Blood.
Blood assumes an essential part of controlling the bodys frameworks and looking after homeostasis. It performs many capacities inside the body including. Providing oxygen to tissues bound to hemoglobin which is conveyed in red cells.
Principle of blood grouping There are two principles 1-almost all normal healthy individuals above 3-6 months of age have naturally occurring Abs to the ABO Ags that they lack These Abs termed naturally occurring because they were thought to arise without antigenic stimulation 7. Not all blood types are compatible so its important to know your blood group. Receiving blood thats incompatible with your blood type could trigger a dangerous immune response.
The ABO blood group system is the most important blood group system regarding human blood transfusion. The associated anti A and anti B antibodies are usually Immunoglobin M. These antibodies are produced in the first few years of life be sensitization to a variety of foods bacteria and viruses.
The Rh blood group system is the second most. Blood group classification of blood based on inherited differences in antigens on the surfaces of the red blood cells. The most well-known classification the ABO blood group system was developed by Austrian-born American biologist Karl Landsteiner in 1901.
There are four major blood groups determined by the presence or absence of two antigens A and B on the surface of red blood cells. In addition to the A and B antigens there is a protein called the Rh factor which can be either present or absent creating the 8 most common blood types A A- B B- O O- AB AB-. The ABO group system is important during blood donation or blood transfusion as mismatching of blood group can lead to clumping of red blood cells with various disorders.
It is important for the blood cells to match while transfusing ie. Donor-recipient compatibility is necessary. For example a person of blood group A can receive blood either from group A or O as there are no antibodies for A and O in blood group.
Types of Blood Groups and their Characteristics. For any living organism to survive in this world they require proteins nutrients and oxygen. For transfer these substances to all parts of cells of the body their need to be some transport.
Blood acts as transporter in the body. The importance of antigens and antibodies. The red cells of an individual contain antigens on their surfaces that correspond to their blood group and antibodies in the serum that identify and combine with the antigen sites on the surfaces of red cells of another type.
The reaction between red cells and corresponding antibodies usually results in clumping agglutinationof the red cells. Among these ABO blood grouping system is the most important system for screening transfusion and transplantation practice today. ABO blood grouping system divides blood into 4 groups ABABO based on the presence or absence of antigens A and B on the RBC surfaces and naturally occurring antibodies anti-A and anti-B on serum.

The process of identifying a persons blood group by serologic testing of a blood sample. Also called blood typing.
These are known as ABO blood groups and are determined by whether an individuals red blood cells RBCs carry the A antigen the B antigen both A and B antigens or neither. From early childhood healthy individuals produce antibodies against the A or B antigens that are not present in their own blood McLelland 2001.
