Rh Blood Group System
The Rh (Rhesus) blood group system (including the Rh factor) is one of thirty current human blood group systems. Clinically, it is the most important blood group system after ABO. At present, the Rh blood group system consists of 50 defined blood-group antigens, among which the five antigens D, C, c, E, and e are the most important. The commonly used terms Rh factor, Rh positive and Rh negative refer to the D antigen only. Besides its role in blood transfusion, the Rh blood group system—specifically, the D antigen—is used to determine the risk of hemolytic disease of the newborn (or erythroblastosis fetalis) as prevention is key.

Famous quotes containing the words blood, group and/or system:
“The stars move still, time runs, the clock will strike,
The devil will come, and Faustus must be damned.
O I’ll leap up to my God: who pulls me down?
See, see, where Christ’s blood streams in the firmament.
One drop would save my soul, half a drop, ah my Christ.”

“Whoever places his trust into a system will soon be without a home. While you are building your third story, the two lower ones have already been dismantled.”
