The RHD gene codes for the RhD erythrocyte membrane protein that is the Rh factor antigen of the Rh blood group system. [6] RHD has sequence similarity to RHCE, RhAG, RhBG, and RhCG and these five genes constitute the Rh family. It was proposed that the erythrocyte Rh complex is a heterotrimer of RhAG, RhD, and RhCE protein subunits. [7] RhAG ...
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
Rhesus factor testing utilizes genotyping to detect the presence of the RhD gene. By checking the existence of the RhD gene in the individual's genome, the presence of Rhesus D (RhD) antigens can be inferred. Individuals with a positive RhD status have RhD antigens expressed on the cell membrane of their red blood cells, whereas Rhesus D ...
The gene codes for the RhD protein on the red blood cell membrane. D− individuals who lack a functional RHD gene do not produce the D antigen and may be immunized by D+ blood. [citation needed] The D antigen is a dominant trait. If both of a child's parents are Rh negative, the child will definitely be Rh negative.
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).
PCR to detect RHD (gene) gene exons 5 and 7 from cffDNA obtained from maternal plasma between 9 and 13 weeks gestation gives a high degree of specificity, sensitivity and diagnostic accuracy (>90 percent) when compared to RhD determination from newborn cord blood serum. [53] Similar results were obtained targeting exons 7 and 10. [56]

Rh o (D) immune globulin (RhIG) is a medication used to prevent RhD isoimmunization in mothers who are RhD negative and to treat idiopathic thrombocytopenic purpura (ITP) in people who are Rh positive. [2] It is often given both during and following pregnancy. [2] It may also be used when RhD-negative people are given RhD-positive blood. [2]
