What is Dutch cortisol awakening response?

The DUTCH Cortisol Awakening Response (CAR) test measures your cortisol levels at specific times around waking using saliva samples. This unique pattern reflects your body's ability to respond to stress and is an important indicator of overall adrenal health and resilience.

Why is this test important?

An abnormal CAR can indicate chronic stress, burnout, or other adrenal dysfunctions that impact energy, sleep, and immune function. Understanding your CAR helps practitioners tailor strategies to support adrenal health, improve stress management, and enhance overall vitality.

How to Prepare

Specific collection instructions will be provided with the test kit. It typically involves collecting saliva samples at precise times immediately upon waking and at intervals thereafter.
