Patient Brochure

The Cortisol Awakening Response (CAR) test is a unique assessment measuring the predictable rise and fall in cortisol within the first hour of awakening.  The test is essential in evaluating the overall function of the HPA axis. In this particular test we measure cortisol immediately on rising, 30 minutes post waking, 60 minutes post waking, 12:00 (noon), 4:00pm and 8:00pm.

The CAR test allows your physician to determine how healthy your HPA axis is which is a good tool for overall health status.

The CAR test is an appropriate tool in practice for most of your patients as it provides an easy assessment of their ability to deal with stressors and is also reflective of how well they have dealt with stressors in the past.
