Method Description Describes how the test is performed and provides a method-specific reference
The substrate acetylthiocholine is split by acetylcholinesterase into thiocholine and acetate. The thiocholine then reacts with dithiobisnitro benzoic acid (Ellmans Reagent) to form the colored product thionitrobenzoic acid which is measured at 405 nm.(Ellman GL, Courtney KD, Andres V Jr, Featherstone RM: A new and rapid colorimetric determination of acetylcholinesterase activity. Biochem Pharmacol 1961;7:88-95)
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.
