Cortisol Test

STRESS HORMONE TEST AND ADRENAL FUNCTION ANALYSIS

Understand how your body responds to stress and uncover the root causes of fatigue, anxiety, or burnout.

The Cortisol Test from Steve Grant Health provides a complete picture of how your adrenal glands and stress hormones function throughout the day. Using simple saliva samples, this assessment measures Cortisol and DHEA at multiple points, including the Cortisol Awakening Response (CAR), a key indicator of how your body reacts to daily stress.

If you struggle with fatigue, poor sleep, anxiety, or difficulty recovering from stress, this test offers critical insights into your adrenal and hormonal balance, helping you take targeted steps to restore resilience.

What is the Cortisol Test?

Also known as the Comprehensive Adrenal Stress Test with CAR, this analysis measures how your stress hormones fluctuate across the day, from morning to evening, providing a complete profile of your adrenal rhythm and stress response.

By tracking Cortisol and DHEA levels at multiple intervals, the test can identify patterns such as:

• Elevated morning cortisol (linked with anxiety, early waking, or high stress)
• Blunted cortisol output (associated with burnout or chronic fatigue)
• Disrupted daily rhythm (affecting sleep, energy, and focus)

Together, these results offer a powerful window into how well your body is coping with physical, emotional, or environmental stressors.

Who is this test for?

This test is ideal for anyone experiencing:

• Persistent fatigue or low energy
• Difficulty managing stress or recovering from busy periods
• Sleep disturbances or early waking
• Anxiety, irritability, or mood changes
• Hormonal imbalances or perimenopausal symptoms
• Recurrent infections or poor immune resilience

It is also beneficial for those experiencing long-term stress or burnout and wish to take a proactive approach to recovery and vitality.

Why test your cortisol levels?

Cortisol plays a crucial role in regulating energy, metabolism, inflammation, and immune function. Chronic stress, poor sleep, and nutrient deficiencies can all disrupt cortisol production, leading to fatigue, poor concentration, and hormonal imbalance.
Testing your cortisol rhythm helps you:

• Identify the stage of stress or adrenal dysfunction (acute, adaptive, or burnout)
• Understand your unique stress hormone pattern across the day
• Tailor nutrition, exercise, and lifestyle strategies to support recovery
• Improve energy, focus, and sleep by restoring adrenal balance

What this test measures

The Cortisol Test measures:

✔ Cortisol at multiple points during the day (morning, noon, afternoon, evening)
✔ Cortisol Awakening Response (CAR) – immediate response upon waking
✔ DHEA – the balancing hormone to cortisol that supports recovery and resilience
✔ Cortisol-to-DHEA ratio – helps determine whether you are in a stressed or adaptive state

These data points provide a clear understanding of your stress physiology and how your body adapts to pressure.
