The Cortisol Awakening Response – also called CAR – reveals more detailed clues that help in assessing adrenal hormone/HPA Axis dysfunction. This testing is often useful for cases of PTSD, major depression, chronic fatigue syndrome and other severe stress conditions.
During a normal cortisol awakening response, adrenal hormone levels should increase 50% in the first 30 minutes after waking for the day and then begin to progressively drop through the afternoon and evening. To capture this response, three – rather than one – morning saliva collections are needed to properly chart the diurnal cortisol curve.
Cortisol Awakening Response Profile contains DHEA [DS] and a six cortisol sample points [C x6]
Cortisol Awakening Response Sample Collection
Saliva testing has long been used as an accurate and reliable method for measuring cortisol because it’s simple and non-invasive, and patients can collect these samples multiple times per day. It’s easy to assess DHEA in these samples too. The Cortisol Awakening Response Test Kit includes 6 small tubes for collecting saliva samples upon waking, 30 minutes after, 60 minutes after, and at noon, evening, and nighttime to assess the response of the HPA axis by measuring fluctuating DHEA-S and cortisol levels.
