  • Storage. Refrigerate.

Use:

Determination of ABO blood group and Rh type for transfusion candidates. Group and typing of expectant mothers and newborns may indicate the potential for ABO hemolytic disease of the fetus/newborn. Rh typing is used to determine Rh immune globulin candidacy for prenatal and postpartum patients.

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.

Methodology:

Hemagglutination
