Rh o (D) Immune Globulin Intravenous [Human; Anti-D] is indicated for use in non-splenectomized, Rh o (D)-positive children with chronic or acute ITP, adults with chronic ITP, and children and adults with ITP secondary to HIV infection. Anti-D must be administered via the intravenous route when used in clinical situations requiring an increase ...
Immunoglobulin D (IgD) is an antibody isotype that makes up about 1% of proteins in the plasma membranes of immature B-lymphocytes where it is usually co-expressed with another cell surface antibody called IgM. IgD is also produced in a secreted form that is found in very small amounts in blood serum, representing 0.25% of immunoglobulins in serum.
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 D-antigen. The term "Rh Disease" is commonly used to refer to HDFN due to anti-D antibodies, and prior to the discovery of anti-Rh o (D) immune globulin, it was the most common ...

The D antigen is the most immunogenic of all the non-ABO antigens. Approximately 80% of individuals who are D-negative and exposed to a single D-positive unit will produce an anti-D antibody. The percentage of alloimmunization is significantly reduced in patients who are actively exsanguinating. [14]
The discrepancy can be resolved by testing the person's red blood cells with an anti-A 1 reagent, which will give a negative result if the patient belongs to the A 2 subgroup. Anti-A 1 antibodies are considered clinically insignificant unless they react at 37 °C (99 °F). Other subgroups of A exist, as well as subgroups of B, but they are ...

Rh blood group, D antigen also known as Rh polypeptide 1 (RhPI) or cluster of differentiation 240D (CD240D) is a protein that in humans is encoded by the RHD gene. [ 5 ] The RHD gene codes for the RhD erythrocyte membrane protein that is the Rh factor antigen of the Rh blood group system . [ 6 ]
