Red cell phenotype (to include Rh and K)

Category Blood Transfusion
Test background

When an antibody has been identified, the patient's red cells should be phenotyped using a reagent of the same specificity as the assigned specificity. The patient's red cells, as determined during phenotyping, will normally be expected to lack the antigen(s) corresponding to the antibody specificity (specificities) assigned. Once established, this information can be used to select donor red cells that would not initiate a transfusion reaction.

Clinicial Indications

To establish the Rh and K red cell phenotype prior to transfusion or in pregnancy.
