Immunoassay for the in vitro quantitative determination of digoxin in human serum and plasma. Measurements are used in the diagnosis and treatment of digoxin overlose and in monitoring levels of digoxin to ensure proper therapy. The electrochemiluminescence immunoassay "ECLIA" is intended for use on Elecsys and cobas e immunoassay analyzers.

The Elecsys Digoxin assay employs a competitive test principle using a monoclonal antibody specifically directed against digoxin. Digoxin in the sample competes with the added digoxin derivative labeled with biotin for the binding sites on the ruthenylated antibody-complex. Results are determined via a calibration curve which is instrument- specifically generated by 2point calibration and a master curve provided via the reagent barcode. The reagent working solutions include: RackPack (kit placed on instrument) M: Streptavidin-coated microparticles, R1: Anti digoxin AbRu(bpy) 3+ and R2: Digoxin-derivativebiotin. PreciControl Cardiac II is a lyophilized control serum based on human serum in two concentration ranges. The controls are used for monitoring the accuracy and precision of the Elecsys CK MB, CK MB STAT, Myoglobin, Myoglobin STAT, proBNP II, proBNP II STAT, and Digoxin immunoassays.
