  • Cortisol Level Test (Cortisol Awakening Response - CAR) is accurately assessing DHEAS & Cortisol hormone levels 6 times during the day.
  • Cortisol Awakening Response also called CAR reveals more detailed clues that help in assessing adrenal hormone/HPA Axis dysfunction.
  • This hormone 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 Test requires a saliva sample. 
  • Test sample can be collected at the comfort of your home.

Cortisol Awakening Response Sample Collection

6-Tube Collection: Six cortisol collections in 24 hours is the most common method for assessing CAR. Start saliva collection within five minutes of waking for the day, followed by a second sample at 30 minutes, and a third sample at 60 minutes. The rest of the diurnal rhythm can be assessed at the normal time intervals – noon, evening and night (shown below).

4-Tube Collection: Alternately, CAR can be assessed with four cortisol collections in 24 hours. When using this method, collect a sample immediately upon waking, 30 minutes after waking, then at noon or evening, and night.
