Antigen-Antibody Reaction

Clinical Significance

To identify female patients who should receive injections of Rh immune globulin (RHIG) during and/or immediately after their pregnancy. Administration of Rh immune globulin will to prevent the sensitization of an Rh negative mother to the D antigen of an Rh positive infant. It will also deter development of hemolytic disease of the newborn (HDN) in subsequent pregnancies.

The administration of a concentrated solution of D antibodies to Rh negative mothers who deliver Rh positive infants or whose pregnancies are terminated early prevents immunization of the mother to the D antigen.A standard dose of 300.0 µg Rho Immune Globulin (RhIG) will neutralize up to 15.0 mL of Rh positive packed red cells or 30.0 mL of fetal whole blood.Administration of Rh immune globulin (RHIG) at 28 weeks of pregnancy prevents sensitization of Rh negative mothers caused by undetected fetal-maternal bleeds in the third trimester. At this time, the patient is screened for candidacy with tests for D, weak D, and unexpected antibodies. Since the patient is an outpatient at this time, special protocols have been established to accommodate the situation. Also, if a patient has had a miscarriage or terminated a pregnancy at less than 12 weeks she must be screened for candidacy with tests for D, weak D and unexpected antibodies. In addition, patients who miscarry or terminate a pregnancy at more than 12 weeks must be screened for fetal-maternal bleed.
