Diurnal Cortisol Test (4x)
Available across US except in NY, NJ, MD and RI.
The 4x diurnal cortisol saliva test will measure your levels using four saliva samples within 24 hours: morning, noon, evening, and night. A physician will review the results to assess whether your levels follow the natural 24 hour diurnal rhythm.
We also offer a AM-PM cortisol saliva test (2x) using morning and evening samples.
