Method Description Describes how the test is performed and provides a method-specific reference
The lipase method is an enzymatic colorimetric method in which lipase catalyzes the hydrolysis of a natural 1,2-diglyceride to form monoglyceride and fatty acid. Monoglyceride is hydrolyzed by monoglyceride lipase to form glycerol and fatty acid. Glycerol is then phosphorylated by glycerol kinase in the presence of ATP to form glycerol-3-phosphate, which is oxidized by glycerol-3-phosphate oxidase to form dihydroxyacetone phosphate and hydrogen peroxide. Subsequently, hydrogen peroxide reacts with 4-aminoamtipyrine and sodium N-ethyl-N-(2-hydroxy-3-sulfopropyl)-m-toluidine in the presence of peroxidase to form quinone diimine dye. The dye absorbs light at 550 nm. The rate of increase in absorbance at 550 nm is directly proportional to the pancreatic lipase activity in the specimen. The method is sensitive and specific for pancreatic lipase and utilizes co-lipase and deoxycholate as activators.(Package insert: Equal Diagnostics Lipase reagent, Exton, PA)

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
Monday through Sunday; Continuously
