14678-7
LaboratoryCortisol [Moles/volume] in Serum or Plasma --PM trough specimen
Definition
Identifies an evening specimen when cortisol is at its lowest point in a circadian cycle -often considered to be midnight. Some laboratories will call this "12AM (midnight)" specimen, but specimens in the range of 11PM to 1AM are acceptable. The trough time may have to be adjusted for patients on different work shifts because their circadian rhythms can shift with their sleeping time.
