Adrenal Fatigue Test

Assess your cortisol rhythm and adrenal function with targeted functional testing.

If you feel constantly exhausted, overwhelmed by stress or unable to recover properly, adrenal function testing may help identify patterns that are contributing to your symptoms. At Perpetual Wellbeing, our degree-qualified naturopaths use adrenal testing to better understand your stress response and guide personalised treatment plans.

Adrenal Function Testing At Perpetual Wellbeing

Feeling tired all the time is common, but that does not make it normal.

If you are waking unrefreshed, relying on caffeine to get through the day, feeling flat in the afternoon or struggling to cope with stress, your adrenal function and cortisol rhythm may be worth investigating.

The adrenal glands produce key hormones involved in energy, metabolism, immune function, blood pressure and the body’s response to stress. When your stress response is under ongoing pressure, it can affect adrenal function and how you feel physically, mentally and emotionally.

At Perpetual Wellbeing, we offer adrenal function testing to help assess your cortisol pattern and related stress hormones. This gives your practitioner objective information to support a more targeted treatment plan, rather than relying on symptoms alone.

What Is An Adrenal Fatigue Test?

An adrenal fatigue test, more accurately described as an adrenal function test or cortisol test, assesses how your adrenal hormones are behaving throughout the day.

Cortisol is one of the body’s primary stress hormones. It naturally follows a daily rhythm, usually rising in the morning to help you wake and gradually declining throughout the day to support rest and sleep at night.

When this rhythm is disrupted, you may feel tired in the morning, sluggish during the day, alert at night or unable to recover properly from stress. Adrenal function testing can help identify whether your cortisol levels are high, low, flat or irregular at different points in the day.

Depending on your symptoms and health history, your practitioner may recommend saliva, urine or blood testing to assess adrenal function and related hormone patterns.

Why Consider Adrenal Function Testing?

Many people seek an adrenal fatigue test when they feel persistently exhausted but standard blood tests have not clearly explained why.

Adrenal function testing may be considered if you experience:

Anxiety
Fatigue (fluctuates throughout the day, morning fatigue, energy at night)
Hypoglycaemia
Lack of stamina
Asthma, colds and other respiratory disorders
Decreased immunity
Mild depression
Allergies
Muscle weakness
Brain fog
Post-Traumatic Stress Syndrome

Chronic Fatigue Syndrome
Postural hypotension
Decreased ability to handle stress
Premenstrual syndrome and menopausal symptoms
Alcoholism and drug addiction
Rheumatoid arthritis
Salt cravings
Flu-like symptoms
Sexual dysfunction
General lethargy
Most diseases for which corticosteroids are involved in the treatment

While these symptoms can have many possible causes, adrenal testing may help your practitioner understand whether your cortisol rhythm and stress response are contributing to your overall health picture.

What Does An Adrenal Function Test Show?

An adrenal function test can provide insight into how your body is responding to stress across the day.

Depending on the type of test used, it may assess:

Cortisol levels at different times of the day
Your cortisol awakening response
Whether cortisol is too high, too low or poorly regulated
DHEA or DHEA-S, which may provide further information about adrenal hormone balance
Patterns that may be associated with fatigue, stress, poor sleep or reduced resilience

This information can help your practitioner determine whether your symptoms may be linked to a disrupted stress response, poor recovery, sleep dysregulation or broader hormonal imbalance.

FAQs About Adrenal Function Testing

What is an adrenal fatigue test?

An adrenal fatigue test is a functional test used to assess adrenal hormone patterns, most commonly cortisol levels across the day. It is more accurately described as an adrenal function test or cortisol test. The aim is to understand how your body is responding to stress and whether your cortisol rhythm may be contributing to symptoms such as fatigue, poor sleep, brain fog or low stress tolerance.

What does an adrenal function test measure?

An adrenal function test may measure cortisol levels at different points during the day, and in some cases DHEA or DHEA-S. This helps your practitioner assess whether your cortisol rhythm is high, low, flat or disrupted. The results can provide insight into your stress response, energy patterns, sleep issues and recovery capacity.

Who should consider adrenal function testing?

Adrenal function testing may be suitable for people experiencing ongoing fatigue, burnout, poor stress tolerance, difficulty waking, afternoon energy crashes, poor sleep, brain fog or feeling “wired but tired”. It may also be considered when stress appears to be worsening hormonal, mood or energy-related symptoms.

How is an adrenal fatigue test performed?

Adrenal function testing may be completed using saliva, urine or blood samples. Saliva testing is commonly used to measure cortisol at several points throughout the day. Your practitioner will explain which test is most appropriate, how to collect the samples and whether you need to adjust any supplements, food, caffeine or medications before testing.

Can I do an adrenal function test at home?

Yes, many adrenal function tests can be completed at home using a test kit. If saliva or urine testing is recommended, you will receive instructions on when and how to collect your samples. The samples are then returned to the laboratory for analysis, and your results are reviewed with your practitioner during a follow-up consultation.

What are the symptoms of adrenal fatigue?

Symptoms commonly associated with adrenal fatigue or disrupted cortisol rhythm include ongoing tiredness, difficulty waking, afternoon energy crashes, poor sleep, sugar or salt cravings, brain fog, low mood, irritability, feeling overwhelmed and reduced resilience to stress. These symptoms can have multiple causes, which is why a thorough assessment is important.

How do I get my adrenal test results?

Your adrenal test results are sent to the practitioner who ordered the test. Once the laboratory analysis is complete, your practitioner will review the results with you, explain what they mean and develop a personalised treatment plan based on your symptoms, health history and test findings.

What happens if my cortisol levels are abnormal?

If your cortisol pattern is higher, lower or more irregular than expected, your practitioner will explain how this may relate to your symptoms. Treatment may include nutrition support, lifestyle strategies, sleep support, stress management, herbal medicine or further testing where appropriate. The aim is to support better energy, resilience and recovery.
