How Do You Measure Cortisol Levels

What Does The Test Measure

Measuring Cortisol in Clinical Settings: Pitfalls, Challenges and Promises

Cortisol testing measures the amount of the hormone cortisol in the blood, urine, or saliva. Cortisol is one of several glucocorticoid hormones, which are hormones that help the body control blood sugar levels, regulate the immune system, and assist the body in responding to stress.

It is normal for cortisol levels to change over the course of the day and in reaction to various stressors. The bodys process of producing cortisol requires several steps:

  • An area of the brain called the hypothalamus produces the hormone corticotropin-releasing hormone .
  • CRH travels to another part of the brain called the pituitary gland and triggers the secretion of corticotropin, which is also called adrenocorticotropic hormone .
  • Finally, ACTH is transported to the adrenal glands where it stimulates the production of cortisol.

In this way, cortisol levels reflect whether these different steps are being carried out normally in the body. Additional information may be gathered by conducting a cortisol test along with other tests like the adrenocorticotropic hormone test.

The First Step To Your Cortisol Reset: Get Tested

Here is one of the top questions I receive: Dr. Sara, how should I test my cortisol? I think I may have adrenal fatigue . Theres so many options. Whats the best?

The short answer is: it depends. For years, Ive been ordering a combination of different tests in individual patients, which reflect various and distinct aspects of adrenal function, but Im now getting more interested in diurnal dried urine testing, which Ive described briefly below .

Cortisol is known as the stress hormone because stress triggers cortisol secretion from the adrenal glands. While normal amounts are key to stable blood sugar, blood pressure, and immune function, too much can make you fat loss resistant, raise blood pressure and cardiovascular risk, poke holes in your gut, and shrink your hippocampus in your brainwhere you consolidate memory and regulate emotions.

When it comes to cortisol testing, here are the best options.

  • Hair. Hair is an interesting choice because its quite stable, and its sometimes used in stress studies published in the peer-reviewed scientific literature. I like the test from Accu-metrics to measure the last 90 days of cortisol load. This may predict cardiovascular risk, and its a reliable measure of your allostatic load or your ability to roll with the punches .
  • I prefer dried urine hormone testing because it combines the advantages of saliva testing and 24-hour urine testing .

    How Much Does The Test Cost

    The cost of a cortisol test depends on several factors, including:

    • Whether the test uses blood, urine, or saliva
    • Whether the test is done alone or in combination with other tests
    • Whether the test is repeated
    • Where the test is performed
    • Whether you have health insurance and, if so, the details of your health insurance coverage

    Total charges for cortisol testing can include fees for office visits, blood draws, and/or laboratory analysis. Insurance may cover all or some of these charges, but you may be responsible for deductibles or copayments. For detailed information about the costs of cortisol testing, talk with your doctors office and health insurance provider.

    If you do not have health insurance, talk with your doctor or a hospital administrator about cost estimates and whether any programs are available to reduce testing costs for people who are uninsured.

    Get The Right Amount Of Sleep

    Prioritizing your sleep may be an effective way to reduce cortisol levels. Chronic sleep issues such as obstructive sleep apnea, insomnia, or shift work have been associated with higher cortisol .

    One review of 28 studies in shift workers found that cortisol levels were higher in workers who slept during the day rather than at night .

    Those on rotating shifts have been linked with poorer health outcomes, such as obesity, heart disease, type 2 diabetes, and worsened mental health (

    Practicing good sleep hygiene can help to keep cortisol in a normal rhythm. Keeping a consistent sleep schedule, avoiding caffeine 6 hours before bed, and staying off your cell phone right before bed are effective strategies.

    Cortisol: The Stress Hormone and What You Need To Know For Adrenal ...

    Cortisol is a hormone that is secreted by the adrenal gland. It is the primary mediator of the stress response. The cortisol in your body is a useful indicator of your overall stress levels. Cortisol levels tend to peak during stress, and as we get older, the amount of cortisol produced by the body slows down. This is why we have observed a dip in cortisol levels among older adults. Levels can fluctuate depending on factors such as sleep, exercise, and diet. Cortisol levels are typically measured by blood tests, saliva, or urine. Blood tests are the most accurate way to measure cortisol levels. Saliva tests are also accurate, but can be more difficult to collect. Cortisol levels are also often measured by urine tests, which are only useful for measuring short term or acute stress responses. Some people may be interested in finding out if they are high or low in cortisol, but not necessarily diagnose a disease.

    Is Cortisol A Stress Hormone

    Cortisol is widely known as the stress hormone. However, it has many important effects and functions throughout your body aside from regulating your bodys stress response.

    Its also important to remember that, biologically speaking, there are multiple different kinds of stress, including:

    • Acute stress: Acute stress happens when youre in sudden danger within a short period of time. For example, barely avoiding a car accident or being chased by an animal are situations that cause acute stress.
    • Chronic stress: Chronic stress happens when you experience ongoing situations that cause frustration or anxiety. For example, having a difficult or frustrating job or having a chronic illness can cause chronic stress.
    • Traumatic stress: Traumatic stress happens when you experience a life-threatening event that induces fear and a feeling of helplessness. For example, experiencing an extreme weather event, such as a tornado, or experiencing war or sexual assault can cause traumatic stress. In some cases, these events can lead to post-traumatic stress disorder .

    Your body releases cortisol when you experience any of these types of stress.

    Exercise But Not Too Much

    Which Test is the Best One to Measure Cortisol Levels?

    Depending on the intensity of exercise, it can increase or decrease cortisol.

    Intense exercise increases cortisol shortly afterward but will decrease a few hours later. This short-term increase helps coordinate growth of the body to meet the challenge. Additionally, the size of the cortisol response lessens with routine training .

    Regular exercise has been shown in numerous studies to help improve sleep quality, reduce stress, and improve overall health, which can help lower cortisol over time .

    Interestingly, regular exercise has also been associated with greater resilience to acute stress and may lower negative health effects associated with stress, such as high cortisol .

    That said, overdoing it can have the opposite effect. Therefore, aim for around 150200 minutes of mostly low- to moderate-intensity exercise each week and allow yourself time to rest between workouts.


    Exercising regularly can help you better manage stress and promote good health, which may help lower cortisol levels. That said, avoid overdoing it and aim for around 150200 minutes of low- to moderate- intensity exercise each week.

    How Is The Cortisol Level Test Done

    A blood sample is used to measure cortisol levels. Most blood samples are collected using this process:

    • The flow of blood in the arm is stopped by wrapping an elastic band around your upper arm. This also causes the veins in your arm to become more visible, making it easier to insert the needle.
    • Alcohol is used to clean the site on your skin where the needle will be inserted.
    • The needle is inserted into the vein. This may cause a brief pinching or stinging sensation.
    • Your blood is collected in a tube thats attached to the needle. More than one tube may be needed.
    • The elastic band is removed after enough blood has been collected.
    • As the needle is removed from your skin, cotton or gauze is placed on the site of the needle insertion.
    • Pressure is applied to the area using cotton or gauze. A bandage is used to secure the cotton or gauze.

    At-home cortisol testing kits are also available. You can purchase a test kit online from LetsGetChecked here.

    There are few risks associated with the cortisol level test. The test is done by taking a blood sample from your vein, which may result in some bruising at the site where the needle was inserted.

    In rare cases, the following risks may be associated with having blood drawn from your vein:

    • excessive bleeding
    • an accumulation of blood beneath your skin, which is called a hematoma
    • lightheadedness or fainting

    Cortisol levels are sometimes decreased by:

    • drugs containing androgens

    Higher-than-usual cortisol levels may indicate that:

    How To Measuer Cortisol

    Late night salivary cortisol test instructions

    Cortisol is a hormone thats a major part of your bodys stress response. Cortisol is released in response to stress, which is one of the main reasons people feel the way they do after waking up early. When cortisol is released, it helps you focus your energy and concentrate. But too much cortisol can make you feel anxious, depressed, and depressed. It can also lead to symptoms of anxiety and depression. When you wake up early, your cortisol levels are already high because youve just woken up. This is because youre not yet used to being awake and alert. So, youre likely to be more anxious and tired when you wake up early. Measuring your cortisol levels is a good way to see how your body responds to waking up early. Cortisol can be measured by looking at your saliva. You can buy a saliva test kit or test strips at your local pharmacy. However, this isnt always the best way to measure cortisol levels. A urine test is also an option, but its not very convenient. Measuring cortisol levels can also be a good idea if youre having trouble sleeping.

    What Is Cortisols Role In The Body

    One of cortisolâs main functions is regulating your bodyâs response to stressâhence, its nickname of the âstress hormone.â

    When you experience stress, your adrenal glands release cortisol into your body which temporarily increases your blood sugar for a boost of energy and curbs nonessential functions. This process helps you perform better in stressful situations, such as when you are in danger.

    When your body experiences a cortisol imbalance, the amount of cortisol produced in response to any kind of stress can impact important functions in your body as a result of too much or too little cortisol being secreted. Cortisol secretion is mainly controlled by three inter-communicating regions of the body the hypothalamus in the brain, the pituitary gland and the adrenal gland.

    In addition to managing your stress response, cortisol also helps your body regulate a number of other key functions linked to your health.
