TEST ID RHO Rh IMMUNOGLOBULIN (Rhogam)

Important Note

Rh immune globulin is a commercial biological substance used in the prevention of hemolytic disease of the fetus/newborn.  RhIG is a concentrated form of an antibody against the main Rh antigen, "D". It is given to D-negative mothers during pregnancy and in the first 72 hours after delivery of a D-postive baby, in order to prevent them from making anti-D.  RHIG may help to clear any baby D-positive red blood cells from the mother's circulation without inducing an immune response, but it may also directly supress the maternal immune response.

Specimen Required

Inpatients must have an ABO/Rh performed or have a historical blood type in the lab computer system before Rhogam can be given.
