How Are Cortisol Levels Tested

Is There Anything Else I Should Know

How to determine if you have high cortisol levels

Similar to those with adrenal insufficiency, people with a condition called congenital adrenal hyperplasia have low cortisol levels and do not respond to ACTH stimulation tests. Cortisol measurement is one of many tests that may be used to help evaluate a person for CAH.

Heat, cold, infection, trauma, exercise, obesity, and debilitating disease can influence cortisol concentrations. Pregnancy, physical and emotional stress, and illness can increase cortisol levels. Cortisol levels may also increase as a result of hyperthyroidism or obesity. A number of drugs can also increase levels, particularly oral contraceptives , hydrocortisone , and spironolactone.

Adults have slightly higher cortisol levels than children do.

Hypothyroidism may decrease cortisol levels. Drugs that may decrease levels include some steroid hormones.

Salivary cortisol testing is being used more frequently to help diagnose Cushing syndrome and stress-related disorders but still requires specialized expertise to perform.

What Happens During A Cortisol Test

A cortisol test often uses a sample of blood drawn at a lab. But the test may also be done on urine or saliva collected at home. Normally, cortisol levels vary during the day, so your provider may order more than one type of test to get more information about your cortisol levels.

For a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

Blood samples are usually taken twice during the day–once in the morning when cortisol levels are at their highest, and again around 4 p.m., when levels are much lower.

For a cortisol urine test, your provider may ask you to collect all your urine during a 24-hour period. This is called a “24-hour urine sample test.” For this test, you’ll be given a special container and instructions for how to collect and store your urine sample. Your provider will tell you what time to start. The test usually includes the following steps:

In certain cases, a urine test for cortisol may be done on one sample of urine collected in the morning.

A cortisol saliva test is usually done at home with a kit to collect a saliva sample. Your provider will tell you what time to collect your sample. It’s often done at night before you go to bed when cortisol levels are normally lower.

What Do The Results Mean

A cortisol test alone can’t diagnose the cause of abnormal cortisol levels. If your cortisol level isn’t normal, you will usually have more tests to find out what is causing the problem.

High levels of cortisol may be a sign that you have Cushing’s syndrome. It may be caused by:

  • Taking high doses of certain steroid medicines for a long time to treat conditions, such as asthma, rheumatoid arthritis, and lupus
  • Tumors in your pituitary gland or other parts of your body that make too much of the hormone that tells your adrenal glands to make cortisol
  • Tumors in your adrenal glands that make extra cortisol

Low levels of cortisol may mean you have Addison disease or secondary adrenal insufficiency:

  • Common causes of Addison’s disease include damage to the adrenal glands from conditions, such as:
  • Certain infections, such as tuberculosis and HIV/AIDS
  • Common causes of secondary adrenal insufficiency include:
  • Autoimmune diseases
  • Traumatic brain injury
  • The most common cause of low cortisol levels is suddenly stopping steroid medicines after using them for a long time.

    If your cortisol results aren’t normal, it doesn’t always mean you have a medical condition that needs treatment. Cortisol levels can be affected by:

    • Certain medicines, such as birth control pills

    To learn what your test results mean, talk with your health care provider.

    How Does A Cortisol Test Work

    Cortisol can be measured in the blood, urine, saliva or a combination. Your healthcare provider will tell you which test they recommend for you.

    • Blood test: In an office, clinic or lab, a healthcare provider inserts a thin needle into a vein in your arm. The needle collects a small sample of blood into a tube. You might feel a slight sting when the needle goes in.
    • Saliva test: You or a healthcare provider puts a swab in your mouth and waits a few minutes until the swab is saturated with spit. If you do the test yourself at home, your healthcare provider will give you a special kit. Theyll tell you what time to perform the test and how to return the sample.
    • Urine test: Your healthcare provider gives you a container to collect your pee. Most urinary cortisol tests collect all the pee you produce in 24 hours. Your healthcare provider may ask you to store the urine in a cold place, then return it to their office or a lab.

    You may need to repeat cortisol testing twice in one day or multiple times over several days because cortisol levels vary.

    When Should I Get Cortisol Testing


    Your doctor may recommend cortisol testing if they think that you may have a condition that affects your cortisol levels.

    Doctors may initiate cortisol testing if you have a health problem that is unusual for people of your age, such as young adults with hypertension or osteoporosis. They may also recommend cortisol testing if you have a severe health condition that can affect cortisol levels or if your doctor finds an adrenal tumor during imaging tests conducted for an unrelated concern.

    Your doctor may recommend cortisol testing based on your symptoms, especially if you have more than one symptom of high cortisol that worsens with time. Symptoms of high cortisol include:

    • Unexplained weight gain, particularly in children
    • Fat accumulation around the base of the neck
    • A hump-like pad of fat between the shoulders
    • Slow growth in children
    • Unexplained weight loss

    Conditions that cause high and low cortisol levels are rare, and these symptoms are most often caused by other diseases. Thus, a doctor may test for more common conditions before initiating cortisol testing.

    In addition to diagnostic testing, cortisol may be tested as a type of monitoring if you have been previously diagnosed with high cortisol and are taking medications to lower your cortisol levels.

    What Is A Cortisol Test

    A cortisol test measures the level of cortisol in your body. Cortisol is a hormone made by your adrenal glands. The test determines whether you have too much or too little of the hormone.

    The test requires a sample of blood, urine, saliva or a combination. The results can help healthcare providers diagnose:

    • Addisons disease, also known as hypocortisolism or primary adrenal insufficiency. This condition happens when your body has too little cortisol.
    • Cushings syndrome, also called hypercortisolism. The condition occurs when your body has too much cortisol.
    • Tumor affecting the production of cortisol. Various tumors may cause high cortisol levels.

    A cortisol test is sometimes called:

    • Urinary cortisol.

    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:

    What Is A Cortisol Urine Test

    How To LOWER Cortisol Levels? Dr. Berg

    A cortisol urine test is also called a urinary free cortisol test or UFC test. It measures the amount of cortisol in your urine.

    Cortisol is a hormone produced by the adrenal glands, which are located on top of the kidneys. Cortisol is often released in response to physical or emotional stress.

    Cortisol functions by:

    • playing a role in mood regulation
    • playing a role in the metabolism of carbohydrates, fats, and proteins

    Cortisol levels naturally rise and fall throughout the day. Theyre usually highest in the morning and lowest around midnight, but there are also variations that depend on the person.

    When this 24-hour cycle is disrupted, however, the body can produce too much or too little cortisol. A cortisol test can be performed to determine the underlying cause of abnormal cortisol levels.

    There are different types of cortisol tests that may be performed, including blood, saliva, and urine tests. The urine test is done over a period of 24 hours.

    The cortisol urine test tends to be more comprehensive than the other types of cortisol tests. It measures the total amount of cortisol excreted into the urine over a 24-hour period.

    Blood tests or saliva tests, however, only measure cortisol levels at a particular time of day. Some people also find blood tests to be stressful, and since the body releases more cortisol during times of stress, the results may not be as precise.

    Taking A Cortisol Test

    Cortisol can be measured in the blood, saliva, or urine. Because cortisol levels change throughout the day, your doctor will likely recommend that your cortisol test be conducted at a specific time, depending on the purpose of the test.

    Blood samples for cortisol tests are most often collected early in the morning when the level of cortisol in your blood should be at its highest. The blood sample is usually taken from your arm at a medical office, hospital, or lab.

    Saliva for a cortisol test may be collected at a medical office or at home. When testing for high cortisol, your doctor may instruct you on how to collect a sample of saliva late at night while you are at home.

    For a cortisol urine test, you will be provided with containers and detailed instructions about how to collect all of the urine you produce in 24 hours. You will collect this urine yourself and then return it to a lab. For convenience, you may wish to choose a 24-hour period when you expect to be at home.

    How Do You Prepare For A Cortisol Test

    It depends on the type of test youre taking and what your doctor tells you to do.

    If youre getting a salivary test, dont eat, drink, or brush your teeth beforehand. If youre getting a blood test, its important to be well hydrated.

    Try to relax and get some rest, as stress may affect your cortisol levels. Your doctor may ask you to avoid any strenuous physical activity the day before a cortisol test too.

    Why The Test Is Performed

    (A) The images on the test zone of various concentrations of cortisol ...

    The test is done to check for increased or decreased cortisol production. Cortisol is a glucocorticoid hormone released from the adrenal gland in response to adrenocorticotropic hormone . ACTH is a hormone released from the pituitary gland in the brain.

    Cortisol affects many different body systems. It plays a role in:

    • Metabolism of fats, carbohydrates, and protein
    • Nervous system function

    and Addison disease , can lead to either too much or too little production of cortisol. Measuring blood cortisol level can help diagnose these conditions. It is also measured to evaluate how well the pituitary and adrenal glands are working.

    The test is often done before and 1 hour after injection of a medicine called ACTH . This part of the test is called an ACTH stimulation test . It is an important test that helps check the function of the pituitary and adrenal glands.

    Other conditions for which the test may be ordered include:

    • Acute adrenal crisis , a life-threatening condition that occurs when there is not enough cortisol
    • Low blood pressure

    Cortisol Tests For Adrenal Fatigue

    A cortisol test is a very important step when you have Adrenal Fatigue Syndrome . AFS occurs when ongoing stress causes overwork and eventually damage to the adrenal glands. Cortisol testing can help identify both of these stages of AFS.

    When youre in the early stages of AFS, it means that youre constantly stressed. When youre under stress, the NeuroEndoMetabolic stress response activates. This causes changes throughout the body that make you alert and ready to face the cause of the stress. These changes also help protect you from damage. The NEM brings about these changes by prompting the adrenal glands to produce more cortisol. So, if you have a cortisol test while youre in these stages, your levels may be higher than normal, perhaps even abnormally high depending on your body and your stress tolerance.

    The NEM stress response is only designed to be active for short periods. When youre stressed long-term, as too many people seem to be in the modern world, the adrenal glands start to fatigue. They struggle to produce the cortisol levels that your body is demanding, and levels may drop. If you have your cortisol levels tested at this stage, you may have abnormally high levels of the hormone or low levels. It all depends on how far the adrenal dysfunction has gone.

    How Do Cortisol Works

    The hypothalamus and pituitary gland located in the blood sense the volume of cortisol levels in the blood if the cortisol level is too low then it adjusts the amount of hormones made. The adrenal glands pick up on the signals and then balances the amount of cortisol in the blood.

    The daily requirement for cortisol in the blood varies for instance, when the body is on high alert, the cortisol hormone will alter or shut down the function that comes in its way including digestive system, immune system and the growth process.

    Too little of cortisol levels or cortisol deficiency can lead to a health condition called Addisons disease. The main symptoms of Addisons disease are as follows

    • Persistent tiredness
    • Changes in skin and darkening of the scars and skin folds
    • Muscle weakness
    • Low blood pressure
    • Loss of appetite and weight
