Sickle Cell Phenotype (Rh & K)
|Also Known as (Alias)
|D,C,E,c, e and K antigen typing
|Determination of Rh and K antigen phenotype of a sickle cell disease (SCD) patient who is likely to
receive multiple red cell transfusions. The results are needed to be able to provide Rh and K matched red cells to prevent the production of antibodies to these antigens and compare against RBC genotyping results to look for blood group variation that impacts transfusion care.
|Standard test tube methodology, Hemagglutination
|Test dependent on the antigen present
|Additional Test Information
|If the patient has been transfused in the last three months, antigen typing of patient red cells may yield unreliable results due to the presence of donor cells. A pre-transfusion should be used for antigen typing, if available. Sample will be referred to red cell genotyping for other blood group antigens. RBC genotyping can provide this information in recently transfused recipients.
