How to solve any ABO, MN, Rh+- blood group problem - EASY
The ABO blood group system is the most important blood type system (or blood group system) in human blood transfusion. The associated anti-A and anti-B antibodies are usually IgM antibodies, which are produced in the first years of life by sensitization to environmental substances, such as food, bacteria, and viruses. ABO blood types are also present in some other animals, for example rodents and apes, such as chimpanzees, bonobos, and gorillas.
The ABO blood group system is widely credited to have been discovered by the Austrian scientist Karl Landsteiner, who identified the O, A, and B blood types in 1900. Landsteiner originally described the O blood type as type “C“, and in parts of Europe it is rendered as “0“ (zero), signifying the lack of A or B antigen. Landsteiner was awarded the Nobel Prize in Physiology or Medicine in 1930 for his work. Alfred von Decastello and Adriano Sturli discovered the fourth type, AB, in 1902.
Due to inadequate communication at the time, it was subsequently found that the Czech serologist Jan Janský had independently pioneered the classification of human blood into four groups, but Landsteiner’s independent discovery had been accepted by the scientific world while Janský remained in relative obscurity. Janský’s nomenclature is, however, still used in Russia and states of the former USSR, in which blood types O, A, B, and AB are respectively designated I, II, III, and IV. The designation A and B with reference to blood groups was proposed by Ludwik Hirszfeld.
In America, W.L. Moss published his own (very similar) work in 1910.
