$265.00
Doctors Data Adrenal Profile measures salivary cortisol at four points throughout the day plus DHEA and secretory IgA (sIgA). Evaluates diurnal HPA-axis function, stress response, sleep and energy patterns, adrenal steroid physiology, and the relationship between stress, thyroid function, sex hormones, and gut/mucosal immunity.
Description
A More Complete Look at Stress Hormones, Energy, Sleep & Hormone Balance
Cortisol is supposed to change throughout the day. A single cortisol measurement can tell us what the level is at one moment, but it cannot show whether your normal daily cortisol rhythm is intact.
The Doctors Data Adrenal Profile measures salivary cortisol at four different times during the day and combines those results with DHEA and secretory IgA (sIgA).
Together, these markers provide a broader look at the hypothalamic-pituitary-adrenal, or HPA, axis—the system that coordinates the brain's response to stress with adrenal hormone production, circadian rhythm, metabolism, immune activity, blood sugar regulation, and interactions with thyroid and sex-hormone physiology.
Why Someone Might Order This Test
Cortisol abnormalities do not always present as obvious “stress.” Symptoms can appear as fatigue, sleep disruption, anxiety, poor exercise tolerance, brain fog, blood-sugar instability, low libido, or difficulty recovering from illness or chronic stress.
Morning Fatigue or Afternoon Crashes
A diurnal profile can show whether cortisol rises appropriately after waking and whether levels remain adequate through the daytime.
Tired but Wired
Elevated or poorly declining evening cortisol may accompany racing thoughts, nighttime alertness, anxiety, or difficulty falling asleep.
Symptoms Across Several Systems
DHEA and sIgA add information about steroid-hormone physiology and mucosal immune function when fatigue, hormone changes, or digestive symptoms overlap.
Why Diurnal Cortisol Testing Is More Informative Than a Single Cortisol Level
Cortisol follows a strong circadian rhythm. It is normally higher in the morning and gradually declines during the day.
Common Cortisol Patterns and What They May Suggest
Overactivated Morning Response
May accompany waking with anxiety, a racing mind, palpitations, tremulousness, increased blood pressure, or feeling immediately “on edge.”
Difficulty Getting Started
May accompany severe morning fatigue, poor alertness, altered sleep-wake timing, chronic illness, medication effects, or other metabolic stress.
Difficulty Winding Down
May accompany insomnia, nighttime anxiety, racing thoughts, a late “second wind,” or feeling physically tired but mentally alert.
Afternoon Crash
May correspond with low stamina, brain fog, poor concentration, or increased dependence on caffeine or sugar later in the day.
Loss of Normal Diurnal Variation
Chronic illness, circadian disruption, sleep loss, inflammation, and sustained stress can be associated with a flatter daily cortisol pattern.
Match Symptoms to the Curve
Morning anxiety, afternoon exhaustion, or nighttime insomnia can be compared directly with the timing of cortisol secretion.
What This Profile Measures
Cortisol ×4
Diurnal HPA-Axis RhythmCortisol is a glucocorticoid hormone produced by the adrenal cortex in response to signals from the hypothalamus and pituitary gland.
It helps regulate:
- Wakefulness and circadian timing
- Blood glucose between meals
- Blood pressure
- Immune and inflammatory responses
- Energy mobilization during stress or illness
- Adaptation to physical and psychological stress
Four samples help determine whether cortisol is appropriately higher when you need daytime energy and appropriately lower when the body should be preparing for sleep.
DHEA
Adrenal Steroid HormoneDHEA is produced primarily by the adrenal glands and acts as a precursor for downstream androgen and estrogen synthesis in peripheral tissues.
DHEA can add context regarding:
- Age-related hormone changes
- Libido and sexual function
- Adrenal steroid physiology
- Energy and resilience
- Androgen and estrogen balance
- Immune and metabolic function
Looking at DHEA together with cortisol provides a broader view than either hormone alone.
Secretory IgA
sIgA • Mucosal ImmunitySecretory IgA is an important antibody concentrated along mucosal surfaces, particularly the gastrointestinal and respiratory tracts.
It participates in first-line immune defense against:
- Bacteria and other microorganisms
- Food and environmental antigens
- Intestinal contents
- Mucosal inflammatory exposures
sIgA does not diagnose dysbiosis, infection, or intestinal permeability by itself, but it can provide useful context when chronic stress overlaps with digestive complaints, food reactivity, or recurrent immune symptoms.
Cortisol and Anxiety
Anxiety is not simply a psychological symptom. The body's stress-response systems can strongly influence how anxiety feels physically and mentally.
Cortisol works with the sympathetic nervous system to help the body respond to perceived threats.
Possible High-Activation Pattern
- Morning anxiety
- Racing thoughts
- Palpitations
- Internal trembling
- Panic tendency
- Difficulty relaxing
Possible Nighttime Pattern
- Second wind at night
- Difficulty falling asleep
- Frequent awakening
- Mentally alert despite fatigue
- Nighttime rumination
- Waking too early
The value of diurnal testing is that symptom timing can be compared with the actual cortisol pattern.
Cortisol and Fatigue
Fatigue can occur with both excessive and reduced stress-system activation. Symptoms alone cannot tell us whether cortisol is high, low, or simply mistimed.
High Stress Load Can Still Cause Fatigue
Persistent hyperarousal can interfere with sleep, increase glucose demand, and leave a person exhausted even when cortisol is not low.
Reduced Daytime Output
Chronic illness and altered HPA-axis signaling may be associated with low stamina, poor morning activation, reduced stress tolerance, or afternoon fatigue.
The Relationship Between Cortisol and Thyroid Function
The HPA axis and thyroid axis are separate hormonal systems, but they interact continuously.
During illness, inflammation, fasting, calorie restriction, or major physiologic stress, thyroid-hormone metabolism can change.
Cortisol & Stress
Helps regulate stress response, glucose availability, circadian timing, blood pressure, and inflammation.
T4 & T3
Regulates metabolic rate, heat production, cardiovascular function, energy expenditure, and many aspects of brain and muscle metabolism.
Similar Symptoms
Fatigue, poor concentration, sleep changes, anxiety, weight changes, poor exercise tolerance, and temperature intolerance can occur with either system.
Significant physiologic stress can reduce conversion of T4 toward active T3 and increase conversion toward inactive metabolites such as reverse T3.
Cortisol, DHEA, Cholesterol & Sex Hormones
Cortisol, DHEA, estrogen, testosterone, and progesterone all belong to the steroid-hormone family.
Their biochemical starting point is cholesterol.
What is clinically useful is recognizing that adrenal and gonadal hormones are interconnected parts of steroid physiology and may need to be interpreted together when symptoms overlap.
Women
Cortisol and DHEA patterns can be useful when fatigue, anxiety, poor sleep, low libido, irregular cycles, perimenopause, or menopause overlap with estrogen and progesterone changes.
Men
Fatigue, poor exercise tolerance, low libido, mood changes, and sleep problems may require looking at cortisol and DHEA together with testosterone, estradiol, thyroid function, metabolic health, and sleep.
Why Cortisol and Hormone Testing Often Need to Be Interpreted Together
| Symptom | Systems Worth Considering |
|---|---|
| Fatigue | Cortisol rhythm, thyroid, iron/B12, sleep, glucose regulation, sex hormones, mitochondrial function, inflammation |
| Anxiety | Cortisol timing, thyroid excess, estrogen/progesterone shifts, blood sugar, sympathetic activation, neurotransmitter patterns |
| Insomnia | Evening cortisol, circadian disruption, menopause, thyroid excess, glucose instability, stress response |
| Low Libido | DHEA, testosterone, estrogen, thyroid function, sleep, chronic stress, medications |
| Weight Change | Insulin resistance, cortisol, thyroid function, menopause or androgen status, diet, sleep, inflammation |
| Brain Fog | Sleep disruption, cortisol rhythm, thyroid function, sex hormones, glucose regulation, nutrient deficiencies, inflammation |
The Gut–Stress Connection: Why Secretory IgA Matters
The gastrointestinal tract is one of the body's largest immune interfaces with the outside environment.
Secretory IgA helps protect the mucosal surface and interact with microorganisms, food antigens, and other intestinal exposures.
Mucosal Barrier
sIgA participates in immune surveillance and helps maintain a healthy relationship between the intestinal immune system and microbes.
Stress Signaling
The brain communicates with the gastrointestinal tract through autonomic, endocrine, and immune pathways.
Cortisol & Immunity
Stress signaling can alter cortisol and immune activity, which may influence gastrointestinal symptoms and mucosal immune function.
Why This Test Can Be Helpful for Insomnia
Cortisol and melatonin normally follow roughly opposite rhythms.
Cortisol rises toward morning while melatonin rises toward night.
When cortisol remains elevated too late in the day, some patients may experience:
- Difficulty becoming sleepy
- A late-night second wind
- Racing thoughts at bedtime
- Feeling tired but mentally alert
- Frequent nighttime waking
- Difficulty returning to sleep
Conversely, an inadequate morning rise can accompany difficulty waking and delayed daytime activation.

Frequently Asked Questions
Why not just check one morning cortisol level?
A morning cortisol measurement provides only one point in time. Four salivary measurements show the shape of the daily cortisol rhythm and whether cortisol declines appropriately toward evening.
What does a normal cortisol rhythm look like?
Cortisol normally rises around awakening, is relatively highest in the morning, and gradually declines through the day to lower levels at night.
Can high evening cortisol contribute to insomnia?
An elevated or poorly declining evening cortisol pattern can accompany hyperarousal and difficulty falling or staying asleep. Insomnia has many causes, so the cortisol result should be interpreted as part of a broader evaluation.
Why is DHEA included?
DHEA is an adrenal steroid hormone and a precursor for downstream androgen and estrogen metabolism. Measuring it with cortisol gives additional information about adrenal steroid physiology.
What does secretory IgA tell us?
Secretory IgA is part of mucosal immune defense, particularly in the gastrointestinal and respiratory tracts. An abnormal value can provide context for gut and immune symptoms but does not independently diagnose intestinal disease.
Can cortisol affect thyroid function?
The HPA and thyroid axes interact. Significant illness, inflammation, calorie restriction, and physiologic stress can alter thyroid-hormone metabolism, including T4-to-T3 conversion.
What is the relationship between cholesterol and cortisol?
Cholesterol is the biochemical precursor for steroid-hormone synthesis. Cortisol, DHEA, progesterone, estrogen, and testosterone therefore belong to related steroid-hormone pathways.
Is this an adrenal fatigue test?
It is more accurately described as a diurnal cortisol and HPA-axis profile. “Adrenal fatigue” is not a recognized diagnosis of adrenal failure. The profile evaluates cortisol timing, DHEA, and sIgA rather than proving that the adrenal glands are exhausted.
