78988-3
LaboratoryCortisol [Moles/mass] in Hair
Definition
Elevated cortisol levels are associated with Cushing Syndrome (CS), and the severity of CS is associated with the duration and extent of excess glucocorticoid exposure. Measuring the cortisol level in hair can provide information about cortisol levels up to 18 months before the time of sampling, while serum, saliva and urine samples reflect only current systemic cortisol levels. Hair cortisol concentrations vary in accordance with the clinical course and may provide a way to assess cortisol exposure over time. [PMID: 19609841]
