How is the Mira Cortisol different from a 24-hour urinary free cortisol?Updated 3 hours ago
A 24-hour collection integrates free cortisol excretion across a full day and is a guideline-endorsed initial test for Cushing syndrome, typically with at least two collections and creatinine measured to check completeness. A Mira wand tests a single spot void.
Spot urinary cortisol without creatinine correction is not an established screening test, and Mira does not position it as one.
