Limitations:

RHIG is contraindicated for individuals who have had anaphylactic or severe systemic reactions to human globulin as well as individuals known to have a true anti-D. 
Additional Information:

Additional sample may be required if antibody identification testing is indicated.  If additional testing is performed, additional charges/CPT code(s) may apply.

Antenatal RHIG is routinely given to Rh negative women at 26-28 weeks gestation. Antenatal specimens from women over 20 weeks gestation with trauma or vaginal bleeding will need an additional test (Fetal Screen) to determine if a large fetal-maternal hemorrhage has occurred. If this test is positive, a quantitative test is performed to determine the amount of RHIG that should be administered.
Method:

Immune Agglutination
Clinical Significance:

ABO, Rh and antibody detection tests are routinely performed in order to assess a patient's eligibility to receive Rh Immune Globulin (RHIG).

Rh Immune Globulin can prevent immunization to the "D" antigen in "D" negative individuals who have received "D" positive red cells as a result of pregnancy or transfusion.
Use: Discontinued 1/30/21
Reference Ranges: Refer to individual tests.
