Cortisol, 4th Specimen details
What Cortisol, 4th Specimen shows
Cortisol is the main stress hormone made by the adrenal glands, and its level changes through the day and in response to stimulation. This result is the fourth in a series of samples, collected at times set by your clinician, such as across the day or before and after a stimulation or suppression test. Depending on the test, the samples may be blood or saliva. Looking at the series together shows the pattern, for example whether cortisol rises normally after stimulation or falls as expected over the day. A single sample in the series is not interpreted on its own, and timing, stress, sleep and medications all affect results.

Salivary cortisol level, particularly late-night salivary cortisol (LNSC) level, is useful in screening for endogenous Cushing syndrome. Two or more positive results of LNSC tests may be used to confirm Cushing syndrome. LNSC measurement may also be used to monitor for recurrence of Cushing disease [1].
