Method Description Describes how the test is performed and provides a method-specific reference
Deuterated stable isotope (d7-androstenedione) is added to a 0.1-mL plasma sample as internal standard. Androstenedione and the internal standard are extracted from specimens using a solid-phase cartridge and eluted from the cartridge with methanol. The extracts are then dried down under nitrogen, reconstituted with 75 mcL of 70/30 methanol/H2O containing 1 mcg/mL of estriol to prevent adsorption to equipment components and analyzed by liquid chromatography-tandem mass spectrometry using multiple-reaction monitoring.(Taylor RL, Machacek D, Singh RJ: Validation of a high-throughput liquid chromatography-tandem mass spectrometry method for urinary cortisol and cortisone. Clin Chem 2002;48:1511-1519)

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 Friday; 2 p.m.
