How Does The Test Work
Dexamethasone is a manmade version of cortisol. After you take a dose of it, your body should make less cortisol. Thatâs the idea behind the test take some dexamethasone and see whether your cortisol level drops. Usually, the test is done overnight, but it can also be done over 2 days.
There are two doses you can take for the test: low dose and high dose. The low-dose test helps you find out if you have Cushing syndrome or not. You typically get 1 mg of dexamethasone.
Youâd get the high-dose test once you know you have Cushing syndrome. Itâs done to find out whether itâs caused by a tumor on your pituitary gland. The high dose is typically 8 mg.

Eat A Nutritious Diet
Nutrition can influence cortisol for better or for worse.
While all foods can be enjoyed in moderation, being mindful of the foods you eat may alleviate symptoms of stress and help you better manage your cortisol levels.
Regular high added-sugar intake may result in elevated cortisol levels. Interestingly, a high sugar diet may also suppress cortisol release during stressful events, making it more difficult for your body to handle stressful situations (

Understanding The Causes Of Stress
Weekly, I balance this brilliant but busy day job with a plethora of extra-curricular activities: my @wellness_ed side hustle monthly talks and fitness festivals oh, and some semblance of a social life.
Most days this is how it goes:
- 5.40am SAD alarm starts to light my bedroom
- 5.51am jump out of bed
- 5.52am pull on Lycra, brush teeth, wash face
- 6.01am make protein coffee
- 8.01am check emails
- 8.45am get to work
You get the gist and Im sure you recognise the feeling of rushing from one activity to the next, often beginning the next task before youve finished the last. For me, replying to emails with one hand, while using the other to blast dry my hair is the norm. You, too?
However, spinning this many plates is nothing to be proud of where your health is concerned as I came to learn.
On the advice of nutritional therapist Eve Kalinin , who I visited complaining of gas, stomach cramps and general gut woes, I booked a cortisol test.

How Is This Cortisol Urine Test Different From A Cortisol Saliva Test
The Everlywell Sleep & Stress Test uses urine samplesâ âinstead of salivaâ âfor measuring cortisol levels. Urine samples are easy to collect, so this cortisol test is a convenient way to measure your cortisol levels at different times of the day. By taking this at-home lab test, you may be able to learn if you have unusually high or low cortisol levels.
When To Test Cortisol Levels

Doctors recommend cortisol testing for the following circumstances:
- Health conditions affecting the hypothalamus, adrenal, and pituitary glands, like tumors and masses
- People with signs and symptoms of endocrine problems
- Monitoring the cortisol levels of people on steroid medications
For example, doctors may initiate cortisol tests for a young adult with hypertension. Its because your risk of developing cardiovascular diseases increases when you have an excess of cortisol.3
Your doctor may order a cortisol test if you show one or more signs of high cortisol levels. The symptoms include:
- Sudden weight gain
- High blood pressure
- High blood sugar
You can also experience health problems from too little cortisol. In emergency cases, your doctor will ask for a cortisol test if they suspect that your symptoms are due to an acute adrenal crisis.
Other causes of insufficient cortisol are Addisons disease, abrupt discontinuation of steroid medications, removal of the adrenal or pituitary gland, or loss of blood supply to the adrenals.
Adrenal crises occur when your body has insufficient cortisol levels. It is life-threatening and must be treated immediately.4
Adrenal crisis causes a shutdown of almost all organ systems.
The signs of low cortisol levels include:
- Persistent fatigue
- Unexplained weight loss
- Pain in the abdomen
This is why doctors check more common health problems like thyroid conditions first before ordering a cortisol test.

Cortisol Levels Through The Day
Cortisol is a stress hormone. You can test your cortisol levels through the day by looking at your saliva. Its a simple process, and you dont need a fancy kit. For the first test, wash your mouth out with water and spit into a cup. If you dont have access to a sink, you can fill a cup with the saliva from your cheek. Take a mouth swab, which you can buy at a pharmacy. If you dont want to use your own saliva, there are now kits that you can buy at drug stores. Then, leave the saliva in the cup at room temperature for a few hours. You want to do this during the morning, because youre most likely to be stressed during the day. After a few hours, you can send the saliva sample to a lab. They will run the test on the saliva and tell you how much cortisol is present. Based on this, you can figure out whether youre stressed or not. You can use the test on a regular basis, so you can know whether youre stressed in specific situations.
How Is Cortisol Measured
Wondering how to test cortisol levels? First off, itâs helpful to know that urine, saliva, and blood are all widely used for measuring cortisol.
Cortisol urine test – The kidneys filter cortisol out of your bloodstream and into urine, making it possible to test cortisol levels with urine samples. This kind of test measures free cortisolâ âor cortisol that isnât attached to proteins. For that reason, this type of test is also known as a urinary-free cortisol test. The Everlywell at-home Sleep and Stress Test is urinary free cortisol test.
Because itâs easy to collect urine samples at different times throughout the day, urinary free cortisol tests are useful for checking how your cortisol levels change over a 24-hour period, which can help provide insight into sleep problems, stressors, and more.
In addition, urinary free cortisol tests are often used for disease monitoring in patients with Cushing’s syndromeâ âa condition in which the adrenal gland makes too much cortisol.
Cortisol saliva test – Saliva measures cortisol because cortisol circulating in the bloodstream can enter saliva through a biochemical process called diffusion. Cortisol saliva tests measure the bodyâs amount of free cortisol. Late-night salivary cortisolâ âmeasurement of cortisol in a saliva sample collected late at night, often around midnightâ âis a reliable way to screen for Cushingâs syndrome.

Can I Measure Cortisol At Home
People can buy at-home cortisol tests online. These require a blood, urine, or saliva sample that a person collects at home, then sends to the companys labs.
The company returns the test results to the person after a few days or weeks.
However, no studies have investigated the accuracy of at-home cortisol tests. A person should contact a healthcare professional once they have received their results.
When To Call A Doctor
While home testing is a convenient method for checking your cortisol, it may be best to see a doctor first if youre experiencing severe symptoms of possible low or high cortisol. These may include sudden, unexplained weight changes, darkened areas of your skin, or significant changes in mood.
You should also see a doctor if you decide to take an at-home cortisol test and you receive abnormal results. They may order follow-up tests and determine an appropriate treatment plan. Its also important to communicate any at-home test results with a doctor if youre currently being treated for Cushing syndrome or Addison disease.
Finally, if you receive normal at-home cortisol results but still dont feel right, make an appointment with your doctor to help determine what could be the underlying cause of your symptoms.

How To Do Cortex Testing At Home
You can do a lot of things to improve your mental health in one simple day of changing your lifestyle. But, one of the most simple and effective ways to combat stress is through exercise. Many studies have shown that physical activity can help combat anxiety and depression. But, it can also do wonders for your physical health, especially if youre stressed out. Exercise can also increase your CORTEX. This is one of the three hormones that help maintain mood. Cortisol is responsible for helping your body deal with stress. Too much cortisol can actually lead to depression and anxiety. By getting more exercise you can increase your CORTEX, which in turn can help fight against stress. The most common way to measure your CORTEX is through saliva testing. Heres how to test for it.
Common Symptoms Of Elevated Stress And Sleep Deprivation:
- Cant get to sleep or stay asleep
- Frequent or early waking
- Feeling âtired but wiredâ
If you are having issues related to sleep or stress, taking an at-home cortisol test may be helpful for you to understand what may be causing your symptoms.
Cortisol regulates how much sugar and fat gets stored in your body and how much is released to use for fuel. Thatâs why a cortisol imbalance can lead to changes in weight, energy, and other symptoms.
Cortisol is also your bodyâs main stress hormone. When your body is stressed, your adrenal glands release a burst of cortisol, sending blood flow into your muscles and increasing your blood sugarâ âgiving you a boost of energy. Stressors can be psychological or physiological , and various activities of day-to-day living all cause physiological stress that results in spikes of cortisol.
But lots of stress for a prolonged amount of time can lead to chronically elevated cortisol levels. This may increase your risk of health issues including:
- Increased weight
- Difficulty remembering
Cortisol testing can be useful because it can help you see if your cortisol levels are very high -potentially causing symptoms-so you can discuss possible next steps with your healthcare provider.

The Importance Of Cortisol Testing In Afs
A cortisol test is essential when you think that you have AFS. Its a useful marker of the health of your adrenal glands, indicating potential problems. Because of the interconnection between the adrenal glands and the other components of the Hormonal Circuit, it can also indicate that you need to take steps to care for the thyroid and reproductive organs as well. Trying to improve the health of the adrenals alone may help a little. But because of the interaction between the components of the Hormonal Circuit, it may not be enough to produce lasting improvement in your health.
Finding a medical professional who understands the interconnected nature of the Hormonal Circuit is essential for this recovery journey. They will be able to guide you on the best strategies to improve adrenal health as well as the health of the Hormonal Circuit as a whole.

How Cortisol Testing Works
The cortisol hormone can be measured using blood, saliva, or urine samples.
Your cortisol levels change the entire day, so your doctor will likely set a specific time to conduct the test.
For example, the cortisol in your blood is at its peak early in the day. In the afternoon, it reaches its lowest value. The blood samples for a cortisol blood test are often collected in the morning.5
Some tests also collect a sample in the afternoon. They check if cortisol levels are dropping as they normally should.
The cortisol in your saliva and the active or free cortisol in your plasma are balanced in the evening. Your doctor will require you to collect the specimen for a cortisol saliva test at night.6
A cortisol urine test requires that you collect all your urine within a 24-hour period. The lab will provide sterile containers for obtaining your urine sample. Theyll also instruct you on how to collect your urine specimen.
How To Check Your Cortisol Levels From The Convenience Of Home
Check on your cortisol levels and other key hormones from the convenience of home with the at-home Sleep & Stress Test. Everything you need for collecting a urine sample at home and shipping it to a CLIA-certified lab for testing is included with the kit. The test results will reveal how your cortisol levels fluctuate throughout a 24-hour period and whether your levels are high or low compared to the reference range.

What Do High Cortisol Levels Mean
High cortisol levels could be a sign of many different conditions. First of all, high cortisol levels upon waking up, or even normal cortisol levels which do not decrease towards the end of the day, could suggest Cushing syndrome. It is important to rule out any contributing factors to these high cortisol levels, such as stress or taking high doses of glucocorticoid medications .
For this, an overnight dexamethasone suppression test is carried out as dexamethasone suppresses ACTH production from the pituitary gland which in turn decreases cortisol production. If you are experiencing stress or you are taking glucocorticoid medication, your cortisol levels should decrease after the dexamethasone suppression test .
With Cushing syndrome, your cortisol levels will remain unchanged, you might have an abnormal production of ACTH from the pituitary gland due to an overactive pituitary gland or an adrenal gland tumour, or in more severe cases a tumour of the pituitary gland. Your doctor might ask you to take your cortisol home test late at night, as it is the best way to determine if you have Cushing syndrome .
Bear in mind that if you are pregnant or if you are having oestrogen therapy, your cortisol levels will be generally higher .
Which Cortisol Test At Home Is Best

There are three different ways to test your cortisol levels: blood, urine, and saliva cortisol tests kits.
Urine and saliva tests measure free cortisol levels while blood cortisol home test kits measure both protein-bound and free cortisol.
This means that a home cortisol blood test can give you a good picture of adrenal gland function and their capacity for total cortisol synthesis and its release into the bloodstream.
