Type A is common in Central and Eastern Europe. In countries such as Austria, Denmark, Norway, and Switzerland, about 45–50% of the population have this blood type, whereas about 40% of Poles and Ukrainians do so. The highest frequencies are found in small, unrelated populations.
The Rh blood group system consisted of 49 defined blood group antigens [ 1 ] in 2005. As of 2023, [update] there are over 50 antigens among which the five antigens D, C, c, E, and e are the most important. There is no d antigen. Rh (D) status of an individual is normally described with a positive (+) or negative (−) suffix after the ABO type ...
An Rh D-negative patient who does not have any anti-D antibodies (never being previously sensitized to D-positive RBCs) can receive a transfusion of D-positive blood once, but this would cause sensitization to the D antigen, and a female patient would become at risk for hemolytic disease of the newborn. If a D-negative patient has developed ...

Rh disease. Rh disease (also known as rhesus isoimmunization, Rh (D) disease, or rhesus incompatibility, and blue baby disease) is a type of hemolytic disease of the fetus and newborn (HDFN). HDFN due to anti-D antibodies is the proper and currently used name for this disease as the Rh blood group system actually has more than 50 antigens and ...
The term human blood group systems is defined by the International Society of Blood Transfusion (ISBT) as systems in the human species where cell-surface antigens—in particular, those on blood cells—are "controlled at a single gene locus or by two or more very closely linked homologous genes with little or no observable recombination between them", [1] and include the common ABO and Rh ...
