Total Cortisol
Measures cortisol, the body's main stress hormone. Levels follow a daily rhythm, so a morning draw is best. Results usually in 1β2 business days.
Cortisol is produced by your adrenal glands and helps regulate stress response, metabolism and blood pressure. It naturally peaks in the morning and falls through the day, so timing matters β a morning sample gives the most interpretable result.
