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 not only the ...
Thus, notwithstanding it is a misnomer, the term survives (e.g., rhesus blood group system and the obsolete terms rhesus factor, rhesus positive, and rhesus negative – all three of which actually refer specifically and only to the Rh D factor and are thus misleading when unmodified). Contemporary practice is to use "Rh" as a term of art ...
This list concerns blood type distribution between countries and regions.Blood type (also called a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs).

In an RhD negative mother, RhIG can temporarily prevent sensitization of the maternal immune system to RhD antigens, with each 100 μg of anti-D being able to neutralize about 4 mL of fetal blood. [13] With the widespread use of RhIG, Rh disease of the fetus and newborn has almost disappeared in the developed world.
Rhesus c HDFN can range from a mild to severe disease and is the third most common form of severe HDN. [19] Rhesus e and rhesus C hemolytic disease of the newborn are rare. Anti-C and anti-c can both show a negative DAT but still have a severely affected infant. [20] [21] An indirect Coombs must also be run.
The NHS said it is the first ever mass home blood type ... 30,000 people will receive home blood type testing kits as the NHS tries to identify 5,000 individuals with critical O negative blood.
In some cases, the direct Coombs will be negative but severe, even fatal HDN can occur. [29] An indirect Coombs needs to be run in cases of anti-C, [30] anti-c, [30] and anti-M. Anti-M also recommends antigen testing to rule out the presence of HDN. [22] Hgb – the infant's hemoglobin should be tested from cord blood. [3]
