Detailed explanation-1: -The Rh factor is one of the proteins on RBCs used to indicate whether the blood of two different people is compatible when mixed – such as blood of a mother and her baby at birth. It is routine and important that the Rh factor for a mother and unborn child be determined during pregnancy.

Detailed explanation-3: -The Rhesus factor, or Rh factor, is a certain type of protein found on the outside of red blood cells. People are either Rh-positive (they have the protein) or Rh-negative (they don’t have the protein). This is important when you’re Rh-negative and pregnant with a fetus who’s Rh-positive.
Detailed explanation-4: -The Rh antigens are expressed as part of a protein complex in the RBC membrane. This complex is only expressed in cells of the erythroid line, and therefore Rh antigens are only expressed in RBCs.
Detailed explanation-5: -Rhesus D (RhD) antigen There are more than 40 different kinds of Rh antigens. The most significant Rh antigen is RhD. When RhD is present on the red cell surface, the red cells are called RhD positive.
