Use
Determination of ABO blood group and Rh type for transfusion candidates. Group and typing of expectant mothers and newborns may indicate potential for ABO hemolytic disease of the fetus/newborn. Rh typing is used to determine Rh immune globulin candidacy for prenatal and postpartum patients.
Special Instructions
If a CBC and/or an antibody screening test is ordered with this test, please submit a separate 4 mL specimen for each test.
Specimen Requirements

ABO blood grouping and Rh typing
Limitations
Abnormal plasma proteins, cold autoagglutinins, positive direct antiglobulin test, and, in some cases, bacteremia may interfere with test interpretation. Variable testing results may be observed with partial antigens, which are rare variants of the D antigen.
