Cortisol, Serum, LC-MS/MS
Method Description Describes how the test is performed and provides a method-specific reference
Liquid chromatography with triple quadrapole mass spectrometer:deuterated cortisol (d4-cortisol) is added to each specimen as an internal standard. Cortisol and d4-cortisol are extracted from the samples with methylene chloride and analyzed by liquid chromatography-tandem mass spectrometry using multiple reaction monitoring. A calibration curve is included with each batch of patient samples.(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;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.
