Adrenal testing is a diagnostic evaluation that measures the hormones produced by the adrenal glands — primarily cortisol, DHEA-S, aldosterone, and catecholamines (adrenaline and noradrenaline). These hormones govern your stress response, blood pressure, metabolism, immune activity, and energy production.
When these hormones fall out of balance — whether too high, too low, or disrupted in their daily rhythm — the consequences are far-reaching. Adrenal testing gives physicians objective data to determine what is actually happening inside your endocrine system, rather than relying on guesswork.
Research published in the Journal of Clinical Endocrinology & Metabolism indicates that hypothalamic-pituitary-adrenal (HPA) axis dysregulation is significantly more common than previously recognised, affecting a wide range of patients presenting with chronic fatigue, mood disorders, and sleep disturbances — many of whom had previously received normal results on standard blood panels.
Understanding the difference between healthy and disrupted adrenal function is essential context for interpreting test results.
When this rhythm is disrupted — whether cortisol is chronically elevated, chronically suppressed, or reversed — patients experience the wide-ranging symptoms commonly associated with adrenal dysfunction.
Adrenal hormone imbalance can affect multiple body systems simultaneously, which is why it is frequently missed or misattributed in standard medical workups. Many patients have seen multiple doctors before receiving an accurate assessment of their adrenal function.
Symptoms that may indicate adrenal dysfunction include:
If you are experiencing several of these symptoms together, a comprehensive adrenal hormone panel can help determine whether HPA axis dysfunction is contributing to your health challenges.
Adrenal testing is appropriate for a broad range of patients. You may benefit from adrenal hormone testing if you:
Importantly, adrenal dysfunction does not always appear in standard blood panels. Comprehensive adrenal testing — particularly four-point saliva cortisol panels — often reveals patterns that conventional testing misses.
At Patients Medical, our physicians select the most appropriate testing method based on your symptoms, medical history, and clinical presentation. In many cases, a combination of tests provides the most complete picture.
A 24-hour urine collection measures the total cortisol excreted by the kidneys over an entire day, providing a cumulative picture of cortisol output. This test is less sensitive to moment-to moment fluctuations and is particularly useful for identifying sustained cortisol excess.
Best used for: Ruling out or confirming Cushing’s syndrome, assessing total cortisol burden,
evaluating adrenal hyperactivity.
A cortisol blood test measures the level of cortisol in the bloodstream at a specific point in time. It is most informative when drawn early in the morning (between 7am and 9am), when cortisol levels are at their natural peak.
A low morning cortisol reading may suggest adrenal insufficiency or HPA axis suppression. Abnormally high readings can indicate Cushing’s syndrome or chronic stress-driven adrenal overactivation. Blood testing provides an important baseline and is often the starting point for further investigation.
Best used for: Baseline cortisol assessment, screening for adrenal insufficiency or Cushing’s
syndrome, monitoring treatment response.
The saliva cortisol test is one of the most informative tools available for evaluating adrenal function. Rather than a single snapshot, it measures cortisol at four distinct times across the day — morning, noon, afternoon, and evening — mapping the full arc of your cortisol rhythm.
This test is particularly valuable because it captures patterns that a single blood draw cannot detect: a cortisol curve that starts too low, drops too quickly, fails to decline in the evening, or is reversed entirely. These patterns are strongly associated with fatigue, insomnia, and stress intolerance, yet they frequently go undetected on standard panels.
Best used for: Adrenal fatigue evaluation, HPA axis rhythm assessment, chronic stress workup,
sleep and energy pattern analysis.
The ACTH stimulation test (also called the cosyntropin stimulation test) evaluates how the adrenal glands respond when they receive a stimulus from the pituitary gland. A synthetic version of ACTH is administered, and cortisol levels are measured before and after to assess the adrenal glands’ capacity to respond. This is the gold-standard diagnostic test for primary adrenal insufficiency (Addison’s disease) and for evaluating secondary adrenal insufficiency caused by pituitary dysfunction.
Best used for: Diagnosing Addison’s disease, confirming adrenal insufficiency, evaluating
pituitary-adrenal axis integrity.
In addition to cortisol, our physicians often assess DHEA-S (dehydroepiandrosterone sulfate), the adrenal precursor hormone that supports energy, immune function, and hormonal balance. Low DHEA-S is commonly associated with adrenal burnout and ageing-related adrenal decline. This test is often combined with cortisol testing to provide a more complete picture of adrenal reserve.
| Test | What It Measures | Best Used For | Timing | Turnaround |
|---|---|---|---|---|
| Cortisol Blood Test | Single-point serum cortisol | Initial screening, Addison’s/Cushing’s | Morning (7–9am) | 1–3 days |
| Saliva Cortisol (4-point) | Cortisol rhythm across the day | Fatigue, HPA dysfunction, sleep issues | 4 collections per day | 5–7 days |
| 24-Hour Urine Cortisol | Total daily cortisol output | Cushing’s syndrome, cortisol excess | Full-day urine collection | 5–7 days |
| ACTH Stimulation Test | Adrenal reserve and response | Adrenal insufficiency, Addison’s disease | Morning clinic visit | Same day |
| DHEA-S Panel | Adrenal precursor hormone | Adrenal burnout, low energy, ageing | Any time of day | 1–3 days |
Your appointment begins with an in-depth review of your symptoms, health history, lifestyle, stress patterns, sleep quality, and any previous lab results. We take time to understand your complete clinical picture before recommending any testing.
Based on your presentation, your physician will recommend the combination of adrenal tests most likely to reveal clinically meaningful information. We do not use a one-size-fits-all panel.
Blood draws are performed at our Manhattan clinic. Saliva and urine collection kits are provided for home use with clear instructions. Our team is available to answer any questions about preparation and collection.
All samples are processed through accredited clinical laboratories. We partner with specialist labs that offer functional hormone panels with high sensitivity and clinical accuracy.
Your physician reviews results with you in detail, explaining what each marker means and how the findings relate to your symptoms. If adrenal dysfunction is identified, a personalised treatment plan is developed and discussed at this appointment.
The following is an anonymised composite case based on patient presentations at Patients Medical. Individual results vary.
A 44-year-old marketing executive presented to Patients Medical with a three-year history of worsening fatigue, difficulty concentrating, recurrent upper respiratory infections, and a strong dependence on caffeine to function through the afternoon. Her primary care physician had run standard thyroid and CBC panels, all of which returned within normal limits.
At Patients Medical, a four-point saliva cortisol test revealed a significantly blunted morning cortisol awakening response, with cortisol levels remaining flat through the afternoon — a pattern consistent with HPA axis hypoactivity following prolonged occupational stress. DHEA-S levels were also at the low end of the functional range.
Over a 16-week integrative programme incorporating adaptogenic botanical support, targeted nutritional therapy, sleep hygiene optimisation, and a structured stress-reduction protocol, her morning cortisol awakening response normalised. By week 12, she reported her energy levels had returned to those she had experienced in her mid-30s, and she had discontinued her afternoon caffeine dependency entirely.
When adrenal dysfunction is confirmed, Patients Medical offers a comprehensive, root-cause focused treatment approach. Our programmes are individually designed and may include:
Evidence-informed herbs such as ashwagandha, rhodiola rosea, and Siberian ginseng have demonstrated support for HPA axis normalisation and cortisol regulation in peer-reviewed research
Targeted nutritional protocols address deficiencies in magnesium, vitamin C, B-complex vitamins, and zinc — all of which are critical cofactors in adrenal hormone synthesis.
Intravenous delivery of adrenal-supportive nutrients bypasses digestive absorption limitations and provides rapid cellular replenishment for depleted patients.
Where clinically indicated, low-dose hormone support may be considered alongside lifestyle and nutritional interventions.
Our physicians work with patients to identify and address structural lifestyle factors — including sleep hygiene, circadian rhythm disruption, and chronic stressors — that perpetuate adrenal dysregulation.
Long-term adrenal recovery requires sustainable behavioural change. Our team provides practical, evidence-based guidance on exercise, nutrition, and daily rhythm management.
Patients Medical has been a leader in integrative and functional medicine in New York City for over 30 years. Our approach is distinguished by depth of evaluation, personalised care, and a genuine commitment to identifying the root cause of your symptoms rather than managing them in isolation.

In today’s fast-paced world, stress-related disorders are more common than ever. Yet conventional medicine often overlooks one critical system—the adrenal glands. At Patients Medical in New York City, our integrative and functional medicine approach focuses on identifying the root causes of adrenal fatigue and hormonal imbalances, so you can restore energy, clarity, and well-being—naturally.
We don’t just treat your symptoms—we treat the underlying dysfunction that’s draining your vitality.
Your adrenal glands are two small organs located above your kidneys. They produce essential hormones like cortisol, DHEA, and adrenaline—regulating your response to stress, metabolism, energy production, blood pressure, and immune function.
When these glands are overworked or underactive, a condition called adrenal dysfunction or “adrenal fatigue” can develop, leading to a cascade of health issues.
If you experience any of the following, adrenal dysfunction may be a root cause:
Functional medicine helps uncover what’s draining your adrenal glands. These are the most common root contributors:
At Patients Medical, we go far beyond standard blood work. We use cutting-edge labs to assess adrenal function comprehensively:
We customize each plan to restore adrenal health through natural, evidence-based methods:
Jessica, age 39, came to us with extreme fatigue, weight gain, brain fog, and anxiety. Her cortisol curve was completely flat, and she was showing early thyroid decline. We created a 12-week integrative plan:
At the end of three months, Jessica’s cortisol rhythm normalized, her energy soared, and her mood improved dramatically. She was able to return to work full-time and resume regular exercise.
If you are experiencing persistent fatigue, unexplained symptoms, or stress intolerance that has not been explained by standard medical testing, adrenal hormone assessment may provide the answers you have been looking for.
Patients Medical is located in midtown Manhattan and serves patients from across New York City, Long Island, Westchester, and New Jersey. Telehealth consultations are also available for patients outside the metro area.

Adrenal testing evaluates hormone levels produced by the adrenal glands — particularly cortisol, DHEA-S, and aldosterone. It helps diagnose adrenal insufficiency (Addison’s disease), Cushing’s syndrome, HPA axis dysregulation, and chronic stress-related hormonal imbalance. It also provides important context when evaluating thyroid disorders, autoimmune conditions, and unexplained fatigue.
High cortisol is often associated with abdominal weight gain, high blood pressure, anxiety, poor sleep, and a feeling of being “wired but tired.” Low cortisol typically presents as persistent fatigue, dizziness on standing, salt cravings, difficulty recovering from illness, and a blunted stress response. Many patients have a disrupted daily rhythm rather than a simply high or low level — which is why four-point saliva testing is often more informative than a single blood draw.
Adrenal insufficiency (Addison’s disease) is a medically confirmed diagnosis where the adrenal glands cannot produce sufficient cortisol, often due to autoimmune destruction or pituitary failure. Adrenal fatigue is a functional term used in integrative medicine to describe a milder, chronic pattern of HPA axis dysregulation — typically caused by prolonged stress — where cortisol output is diminished but not absent. Both conditions cause significant quality-of-life impairment and are detectable through appropriate testing.
Consumer at-home cortisol kits exist, but they typically only measure cortisol at a single point and lack the clinical context to interpret results meaningfully. At Patients Medical, our physician-supervised four-point saliva cortisol panel maps your full daily cortisol curve and is interpreted by an experienced integrative physician alongside your complete symptom picture and health history.
Blood testing and saliva kit collection can be initiated at your initial consultation. Saliva tests involve four home collections across a single day. The 24 hour urine test requires collecting urine over a full day at home. Lab results typically return within 5–10 business days, and your physician will schedule a follow-up to review findings and discuss next steps.
Standard cortisol blood tests and ACTH stimulation tests are generally covered by insurance when medically indicated. Functional panels such as four-point saliva cortisol testing may not be reimbursed by all plans. Our administrative team can assist with documentation and advise on your specific coverage. Please contact our office before your appointment for specific billing guidance.
Yes. Cortisol blood tests should ideally be drawn between 7am and 9am, when cortisol is naturally at its peak. In the 24 hours before testing, avoid intense exercise, alcohol, and significant emotional stress where possible. For saliva testing, specific collection instructions will be provided, including guidance on medication timing and food avoidance before each collection.
Many patients notice meaningful improvements in energy, stress tolerance, and sleep quality within 4–8 weeks of beginning an integrative treatment programme. More complete HPA axis normalisation — reflected in follow up cortisol testing — typically occurs over a 3–6 month timeline. Factors that influence recovery speed include the severity of dysfunction, sleep quality, diet quality, ongoing stressors, and baseline nutritional status.
In many cases, yes. Mild to moderate HPA axis dysregulation frequently responds well to integrative interventions: evidence-based adaptogenic botanicals, targeted nutritional therapy, IV nutrient support, sleep optimisation, and structured stress management. More severe adrenal insufficiency may require pharmaceutical hormone support in addition to these measures
Adrenal dysfunction rarely exists in isolation. It is commonly associated with hypothyroidism and Hashimoto’s thyroiditis, PCOS, perimenopause and menopause, chronic inflammatory conditions, post-viral fatigue syndromes, and anxiety or depression. Our integrative evaluation considers all of these connections, ensuring that adrenal findings are interpreted within the full context of your health.
Standard medical practice typically tests for adrenal insufficiency (Addison’s disease) using a morning cortisol blood test and, if abnormal, an ACTH stimulation test. These are excellent tools for ruling out severe pathology but do not capture the subtler patterns of HPA axis dysregulation that cause significant symptoms in many patients. At Patients Medical, we use a broader diagnostic framework that includes four-point cortisol mapping, DHEA-S assessment, and a comprehensive functional evaluation to identify patterns that conventional panels can miss.
It’s a term used in functional medicine to describe a state where the adrenal glands are unable to produce adequate stress hormones, often due to chronic stress.
Traditional endocrinology recognizes Addison’s and Cushing’s disease but often overlooks subclinical adrenal dysfunction. We use functional diagnostics to assess these subtle imbalances.
Typically through saliva or urine samples collected at different times of day to assess cortisol and DHEA levels.
Many patients begin to feel improvements within 4–8 weeks, depending on the severity and consistency with the treatment plan.
Not usually. Most cases can be addressed through lifestyle, nutrition, herbs, and bioidentical hormones when appropriate.
Yes—imbalanced cortisol can lead to weight gain, anxiety, depression, and sleep disorders.
Some lab tests may be partially reimbursed. We provide superbills for out-of-network reimbursement.
Absolutely. While it’s common in women, men can also experience adrenal dysfunction, especially under chronic stress.
Thyroid and adrenal health are closely connected. We often assess and support both simultaneously.
Yes—we evaluate the full hormonal picture, including estrogen, testosterone, insulin, and thyroid.
Patients Medical specializes in gently helping the patient identify the root cause of their medical issues and then assist them to recover from their problems to help them move forward to good health.
