The DUTCH Cortisol Awakening Response (CAR) saliva test from Precision Analytical measures the natural increase in cortisol levels upon waking. This specialised test monitors cortisol at multiple points after awakening to provide insight into the body's stress response and adrenal function. Using a non-invasive saliva collection method, it offers a convenient way to assess hormonal patterns related to waking and stress regulation. The test is ideal for those seeking to understand their adrenal health and how their cortisol levels fluctuate throughout the day, particularly during the critical awakening period.
