SPN: An enzyme analyzer for clinical use is a device intended to measure enzymes in plasma or serum by nonkinetic or kinetic measurement of enzyme-catalyzed reactions. This device is used in conjunction with certain materials to measure a variety of enzymes as an aid in the diagnosis and treatment of certain enzyme-related disorders.,UMD: Laboratory analyzers that measure enzymes (e.g., lactate dehydrogenase) in terms of their catalytic activity, expressed in activity units (usually in international units [IU]). The actual mass or molar concentrations are seldom measured because enzymes are present in low concentrations and in a matrix containing a large number of chemically similar proteins and other biochemicals. These analyzers may have adjustable temperature controls and mechanical devices to add reagents and samples automatically and to process multiple specimens in sequence. The progress of the reaction is either recorded to allow the analyst to conform the linearity of the reaction or monitored automat
