Adrenocortex Stress Profile

The Adrenocortex Stress Profile evaluates how your body produces and regulates cortisol throughout the day, giving deep insight into stress physiology, adrenal signaling, circadian rhythm function, and nervous system regulation.

Unlike a single cortisol blood test, this test measures cortisol at multiple points across the day, helping identify whether your body is producing too much stress hormone, too little, or releasing it at the wrong time.

Chronic stress, poor sleep, metabolic dysfunction, and hormonal imbalances often originate from disruptions in the hypothalamic–pituitary–adrenal (HPA) axis. This test helps us identify those disruptions so we can design precision interventions that restore energy, sleep, and metabolic balance.

What This Test Measures

This profile evaluates the daily rhythm of cortisol through multiple saliva samples, typically including:

• Morning cortisol surge (CAR – Cortisol Awakening Response)
• Midday cortisol
• Afternoon cortisol
• Evening cortisol

These measurements help map your entire circadian stress curve.

Why This Test Matters

Many people experiencing fatigue, anxiety, poor sleep, weight gain, or hormonal imbalance are often told their cortisol is “normal” based on a single blood draw.

However, cortisol is a circadian hormone, meaning the timing of its release is just as important as the level itself.

This test allows us to detect patterns such as:

• Flattened cortisol curve (chronic stress burnout)
• High nighttime cortisol (sleep disruption and anxiety)
• Low morning cortisol (morning fatigue and poor energy)
• Elevated daytime cortisol (inflammation and metabolic stress)

Understanding this rhythm helps us correct the underlying stress biology driving multiple health symptoms.

Symptoms This Test Helps Investigate

This test is particularly useful if you experience:

• Chronic fatigue or burnout
• Difficulty waking up in the morning
• Sleep disturbances or waking at night
• Anxiety or nervous system dysregulation
• Weight gain around the abdomen
• Brain fog or poor focus
• Hormonal imbalances
• Blood sugar instability

How the Test Works

This is a non-invasive saliva test performed at home.

You will collect saliva samples at specific times during the day, which allows us to evaluate how cortisol fluctuates across your natural circadian rhythm.

The samples are then analyzed to provide a detailed picture of your HPA axis function.

How We Use This Test at The Longevity Lab

At The Longevity Lab, this test is used as part of our root cause analysis framework.

Your results help us design a precision intervention strategy that may include:

• Nervous system regulation protocols
• Circadian rhythm optimization
• Targeted nutritional strategies
• Adaptogenic and mitochondrial support
• Lifestyle and sleep architecture improvements

The goal is not simply to measure stress, but to restore your body's natural stress resilience and energy production.
