System reagent for the quantitative determination of Cholinesterase activity (E.C. 3.1.1.8) in human serum and plasma on Beckman Coulter Synchron CX® Pro System(s), Synchron LX® Pro System(s) and UniCel® DxC 600/800 System(s). A cholinesterase test system is a device intended to measure cholinesterase (an enzyme that catalyzes the hydrolysis of acetylcholine to choline) in human specimens. There are two principal types of cholinesterase in human tissues. True cholinesterase is present at nerve endings and in erythrocytes (red blood cells) but is not present in plasma. Pseudo cholinesterase is present in plasma and liver but is not present in erythrocytes. Measurements obtained by this device are used in the diagnosis and treatment of cholinesterase inhibition disorders (e.g., insecticide poisoning and succinylcholine poisoning). The method is based on the recommendations of the German Society for Clinical Chemisty (Deutsche Gesellschaft für Klinische Chemie, DGKCh). Cholinesterase catalyses the hydrolysis of butyrytthiocholine to butyrate and thiocholine. Thiocholine reduces yellow hexacyanoferrate (III) to colorless hexacvanoferrate (II). The decrease in absorbance at 410 nm is directly proportional to the cholinesterase activity in the sample.
