The cortisol awakening response (CAR) test is a specific type of adrenal stress test that measures the body's cortisol levels in the morning upon waking, typically within the first 30-60 minutes after waking. This test is performed using saliva to assess the body's stress response and cortisol production during the critical period of awakening, which has been found to be a sensitive indicator of the body's ability to cope with stress.
