Cortisol is the stress hormone. This makes it an ideal biomarker for the study of long-term stress. Researchers suggest that the average concentration of cortisol in the hair of healthy, low-stress individuals is 55pg/mhair (range 40-128pg/mhair). In stressed individuals it is 250pg/mhair (range 182-520pg/mhair).
Our aim for this application is to develop a diagnostic to rapidly quantify cortisol in hair as a biological marker for long-term stress assessment.
