Stress Test

What is a Diurnal Cortisol Test? 

This test is a commonly used tool for assessing adrenal cortisol production. This test is four saliva collections on a single day - typically done upon waking before lunch, dinner, and before bed. The labs then report them on a 24-hour graph. The resulting curve - also called a four-point cortisol curve or circadian cortisol pattern, allows healthcare providers to assess the hypothalamic-pituitary-adrenal axis (HPA axis) or adrenal dysfunction.

Consider this test for: 

• Stress 
• Immune dysfunction
• Chronic fatigue 
• Multiple symptoms of adrenal imbalance
