Cortisol Free [Mass/volume] in Serum or Plasma --AM peak specimen 57824-5
LOINC Code
| LOINC code | 57824-5 | ||
|---|---|---|---|
| name | Cortisol Free [Mass/volume] in Serum or Plasma --AM peak specimen | ||
| description | Identifies a morning specimen when free cortisol is at its highest point in a circadian cycle - often considered to be 8AM. Some laboratories will call this "8AM" specimen, but specimens in the range of 7AM to 9AM are acceptable. The peak time may have to be adjusted for patients on night or evening shifts because their circadian rhythms can shift with their sleeping time. | ||

| component | Cortisol.free^AM peak specimen | ||
| property | MCnc = Mass 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 (AM and morning) of saying the same thing. We chose AM because it is shorter. 'Peak' clarifies that specimen is collected when cortisol is expected to be at the highest level. | ||
