ABO Group & Rh Type
Use
The ABO Group & Rh Type test determines a patient's blood type, specifically ABO and Rh D types. This assessment is crucial for pretransfusion testing, organ/tissue transplantation, evaluation of transfusion reactions, and assessing the risk for hemolytic disease of the fetus and newborn (HDFN). Accurate blood typing is fundamental to ensure compatibility in transfusions and transplants, mitigate reactions, and manage pregnancy-related risks.
Special Instructions
Patients should ensure that red cells are not frozen. Collect lavender (K2EDTA) or pink (K2EDTA) tubes, and transport 3 mL of whole blood, ensuring a minimum of 0.5 mL. Separator tubes should not be used, and the sample should be transported refrigerated. Perform tests Monday through Friday, with reports available in 1-3 days.
Limitations
This test cannot determine the Rh D phenotype if a recent RBC transfusion has occurred without complete transfusion history. Mixed field agglutination may occur and complicate the typing, especially with bone marrow transplants or non Rh specific red cell transfusions. Accuracy depends on proper sample collection and handling.
