Biomarker Reference · RBC Phenotype
Red Blood Cell Antigen Typing (RBC Phenotype) is a clinical biomarker used in infectious-disease assessment. Red-cell antigen typing determines which antigens the patient's own cells carry, using antisera or molecular methods to test for Rh (D, C, E, c, e), Kell, Duffy, Kidd, S/s, and other systems. It is measured in 1 laboratory test on BiomarkersLabs.com.
Red-cell antigen typing determines which antigens the patient's own cells carry, using antisera or molecular methods to test for Rh (D, C, E, c, e), Kell, Duffy, Kidd, S/s, and other systems. Knowing the patient phenotype clarifies which antibodies are alloantibodies (directed against foreign antigens) versus autoantibodies (against self) and informs compatibility when the patient requires transfusion in future.
Antigen typing is performed to select antigen-matched units for patients with multiple antibodies or sickle-cell disease, to determine Rh and Kell status in obstetric alloimmunisation, and to differentiate allo- from autoantibody. It also guides prophylactic matching to prevent further alloimmunisation in chronically transfused patients.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
