Biomarker Reference · Ab ID
Red Blood Cell Antibody Identification (Ab ID) is a clinical biomarker used in infectious-disease assessment. Antibody identification uses an extended panel of reagent cells with defined antigen phenotypes. It is measured in 1 laboratory test on BiomarkersLabs.com.
Antibody identification uses an extended panel of reagent cells with defined antigen phenotypes. By observing which cells react and which do not, the blood bank determines the specificity — for example, anti-K reacts only with Kell-positive cells. Some patients form multiple antibodies, and warm autoantibodies or cold agglutinins can complicate the pattern.
Knowing the antibody identity allows selection of antigen-negative donor units, predicts risk in pregnancy (anti-D, anti-c, and anti-K are the most common causes of severe haemolytic disease of the newborn), and guides further workup when autoantibodies or complex mixtures are present.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
