Blood group by agglutination
Blood group by agglutination
Agglutinin is the process through which cells adhere to each other. The bacterial and viruses have the capacity of agglutinating the blood cells. It is also particular that many agglutinins, especially the food lectins are specifically the blood type. There are particular foods that clump the cells of blood type, but fail to react with another type of cells. Agglutination refers to the clumping of particles. Agglutination is universally used for the identifying method of specific bacterial antigens. This assists in the identity of bacteria. This happens usually owing to the antibody or also other molecules binding the multiple particles as well as joining them. It also brings together the small particles that are left suspended in the solution such that the bigger masses are normally later on precipitated. Agglutination can be referred to a type of allergic reaction owing to the occurrence of cells such that they are found compacted together and assist in preventing foreign materials from entering them. This is normally the effect of an antigen found in the neighborhood of the cells. Agglutination refers to the cluster of cells present in the existence of antibody, namely bacteria or red blood cells. As the clumping reaction takes place quickly as well as is easy to produce, it is found that agglutination is one of the recommended techniques for diagnosis. Red blood cells agglutination is used in the Coombs test as well. Max Von Gruber earlier discovered this term agglutinin and employed this to cause cells agglutination. This was also put to test for typhoid fever. Agglutination reaction was found to have another significant application practically in which the human blood was categorized into typical four types. This was classified depending on the reaction of clumping of the blood serum type. Agglutination made the transfusion of blood easily possible as the physicians are now able to prevent the donor blood if it does not suit the receiver and also avoid the recipient’s blood from clumping. Hemagglutination is one of the particular agglutination forms that entails red blood cells as well as can be used to classify RBC surface antigens or to screen antibodies. It is also possible to test a sample of blood using antibodies A or b as it binds together and in determining the blood group or blood type of any individual. The absence or presence of agglutination visually helps in quick as well as convenient methods of assessing the Rhesus as well as the ABO status of an individual. Agglutination is widely employed for identifying bacterial antigens. The clumping reaction takes place immediately and is easy to produce the results. In this way, agglutination is certainly an essential technique in diagnosis.
