Rh Phenotype (D,C,E,c and e Antigen typing)
| Also Known as (Alias) | D,C,E,c and e antigen typing, complete |
| Indications | Determination the likelihood of hemolytic disease of the newborn in cases of maternal antibody, identify compatible blood for recipients with atypical antibodies, identify phenotypically matched blood for recipients likely to receive multiple red cell transfusions to prevent the production of atypical antibodies. |
| Method | Standard test tube methodology, Hemagglutination |
| Test Information | Test dependent on the antigen present |
| Sample Requirements | EDTA tube. Serum separator gel tube is not acceptable. |
| Requested Volume | 1 full 7 ml EDTA sample |
| Minimum Volume or Pediatric volume | Minimum volume: 1 full 7 ml EDTA sample Pediatric: 1 full 3 ml EDTA sample; neonate: 2 full 0.5 ml EDTA microtainers |
| Sample 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. RBC genotyping can provide this information in recently transfused recipients. |
| Shipping Information | Ship at ambient temperature
