The Cortisol Awakening Response (CAR) test from Precision Analytical measures the natural rise in cortisol levels immediately after waking. This test helps to understand your body’s stress response and daily rhythm by assessing how cortisol changes in the first 30 to 45 minutes after awakening. It uses saliva samples collected at specific times after waking to provide an accurate profile of this vital hormone pattern. CAR testing offers valuable insights for those interested in their adrenal health and overall wellbeing. Collections are typically done over one morning and can be conveniently completed at home.
