1/23/2010 · In 1940 Landsteiner discovered another of blood factor antigen, known as Rh. This discovery resulted from Landsteiner’s studies with Rhesus monkeys. Landsteiner and his colleagues found that when blood from monkeys was injected into rabbits and guinea pigs, it clotted.
Rh factor -The discovery of Rh and its terminology. Rh :-Point 1:-There are total 45 blood group system (including ABO system) of which Rh is one. Rh system .Therefore Rh is one of forty-five known human blood group systems.. Point 2: The Rh blood group system again consists of 49 defined subgroups group antigens.However for clinicians it is sufficient to be familiar with common five antigens D …
The Rh blood group system was discovered in 1940 by Karl Landsteiner and A.S. Weiner. Since that time a number of distinct Rh antigens have been identified, but the first and most common one, called RhD , causes the most severe immune reaction and is the primary determinant of the Rh trait.
The Rh factor was discovered in 1940 by the Austrian scientists K. Landsteiner and A. Wiener. The blood of persons whose red blood cells contain the Rh factor is called Rh-positive. There are several different antigens in the Rh-factor system, including the Hr group, which together with Rh.

It was seen as yet another factor, not much different from the M, N, or P factors—useful for fingerprinting, but not having much more extended implications.

Approximately 15 percent of the population lacks this antigen; such individuals are described as Rh -negative. Although anti-D antibodies are not naturally present, the antigen is so highly immunogenic …
