Cortisol [Mass/volume] in Serum or Plasma --AM peak specimen   9813-7

LOINC Code


LOINC code9813-7
nameCortisol [Mass/volume] in Serum or Plasma --AM peak specimen
descriptionIdentifies a morning specimen when 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.

propertyMCnc  =  Mass Concentration
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemSer/Plas
    Ser  =  Serum
    Plas  =  Plasma
scaleQn  =  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 reasonTo 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.
