LOINC Code
| LOINC code | 14678-7 | ||
|---|---|---|---|
| name | Cortisol [Moles/volume] in Serum or Plasma --PM trough specimen | ||
| description | 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. | ||

| component | Cortisol^PM trough specimen | ||
| property | SCnc = Substance Concentration | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Ser/Plas Ser = Serum Plas = Plasma | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||

| change reason | To avoid two ways (PM and evening) of saying the same thing. We chose PM because it is shorter. 'Trough' clarifies that specimen is collected when cortisol is expected to be at the lowest level. | ||
