The Cortisol Awakening Response (CAR) test from Nutripath measures the natural spike in cortisol that occurs shortly after waking. This test helps provide insight into your body’s stress response and adrenal function throughout the day. By assessing cortisol levels at specific times after awakening, it captures an important aspect of your hormonal rhythm. The CAR test supports health practitioners and individuals interested in understanding daily cortisol patterns and their potential impact on wellbeing.
