Ordering Recommendation
Identify unexpected red blood cell (RBC) antibodies in the patient's serum and, when applicable, in antibodies coating the patient's RBCs. Test is used for prenatal patients only, to identify unexpected RBC antibodies to aid in determining the risk for hemolytic disease of the fetus and newborn (HDFN) and to evaluate the patient for Rh immunoglobulin administration. Do not use this test for nonprenatal patients. For nonprenatal patients, order Antibody Identification Package IRL (0013003).
