Who should take the test?

All of us are familiar with the feeling of being under constant stress and feeling tense. Unfortunately, our body cannot differentiate between whether we are actually in a life-threatening situation or in a daily situation. In both cases the body produces a lot of stress hormones, especially cortisol and adrenalin.

Cortisol is the most important stress hormone besides adrenaline, which is primarily produced in the adrenal cortex. Between six o’clock and eight o’clock in the morning the levels are normally the highest, as a consequence the body wakes up at this time. During the day the cortisol level decreases, so the body can slowly come to rest in the evenings. Between twelve o’clock and four o’clock at night the levels are normally the lowest – if the levels are too high at this time, it can cause a sleeping disorder.

The test analyzes:

  • Diurnal Cortisol (5 cortisol values over the day)

Our Daily Cortisol Test helps you to identify abnormalities in your stress hormones as accurate as possible by measuring the cortisol concentration throughout the day. On the basis of the meaningful value you can then work to reduce your stress, improve your sleep, and live a healthier life.

How does it work?

You collect the samples at home, send them back to us and we will provide you with your level of each hormone and whether your level falls within the reference ranges for your age. In addition to that, the results include graphs showing whether your are in the “green” (=normal/healthy) or “red” (=too high/low) area, making it easy to understand the results.

What will my results tell me?

Your results will provide detailed information about whether your cortisol level is normal, low, or high compared to reference ranges in your age group. You can then discuss the results with your doctor or health practitioner, who can give you further guidance and treatment recommendations.

What guidance will I get along with my results?

Test measures
For the Daily Cortisol Test we analyse:
  • Cortisol (5x)

Cortisol is produced in the adrenal glands. Cortisol is the most important stress hormone besides adrenaline: Stress hormones help the body to react to particular strain. They release energy reserves in order to prepare the body for “escape” or “attack”. During hard, physical work, competitive sports, psychological, physical and mental stress situations, or during a severe illness, the distribution of cortisol is also stimulated.

Cortisol plays an important role in the different metabolic processes in the body. In immune processes, cortisol helps with its anti-inflammatory and anti-allergic effect, and has an important function in maintaining the health of the body.

However: Both too low and too high levels can cause unpleasant symptoms.

It is well known that chronic stress is unhealthy – and stress is, in turn, the most important impulse that causes the increase of the distribution of cortisol. If the cortisol levels are too high, symptoms can include immunodeficiency, depression, physical exhaustion, metabolic disorders, diabetes, obesity and sleeping disorders. Excessively high cortisol levels can indeed cause unpleasant symptoms.

Just the same, excessively low cortisol levels can interfere with general well-being: Cortisol is vital. Apart from the provision of energy reserves, it also plays a role in the cardiovascular health,gastrointestinal health, the immune system and brain functions.

Symptoms the Daily Cortisol Test is suitable for:
  • Fatigue or feeling tired
  • Depression
  • Sleep disturbance
  • Weight gain
  • Mental fatigue
  • Lack of concentration
  • Increased appetite

    I chose this saliva test cause it shows the cortisol levels throughout the day, which can’t be done with the normal blood test physicians use. This test is way more comprehensive and I would definitely recommend this to anyone.

Any Questions?

Here are some of the most frequently asked questions regarding this test. Your question is missing? Please contact us at:

Why is it useful to measure cortisol throughout the day?

A Daily Cortisol Test makes sense for a detailed clarification of the adrenal situation. On the other hand, this test is also suitable for people who e.g. suffer from sleep disorders. During the day the cortisol level drops so that the body can slowly come to rest in the evening. If this is not the case and the "inner clock" of our adrenal glands is off, this can lead to difficulty falling asleep.

What are "stress hormones"?

Stress hormones help the body to react to stress. They release energy to prepare the body for "flight" or "attack". In the case of heavy physical work, competitive sports, psychological, physically and mentally stressful situations or in case of serious illness, their production increases.

What are the symptoms of a cortisol deficiency?

Even a slight deficiency can lead to tiredness, depression, concentration difficulties or sleep disorders. If there is a severe deficiency or if, in addition to a previously untreated adrenal malfunction, a special stress situation (accident / illness / operation) occurs, a so-called Addisonian crisis can occur, which is fatal if left untreated.

How does cortisol affect the body?

Cortisol is a stress hormone produced by the adrenal glands. It plays a crucial role in the body's response to stress, regulating metabolism, immune function, and sleep-wake cycles. Imbalances in cortisol levels can impact overall health and well-being.

What are the normal cortisol patterns throughout the day?

Normally, cortisol levels are highest in the morning, helping to wake up the body, and gradually decrease throughout the day. By nighttime, cortisol levels should be at their lowest. Deviations from this pattern can indicate potential issues with stress regulation.
