How To Test For Cortisol Levels

Treatment Of Cushing’s Syndrome

Adrenal fatigue testing: Which test is best? (urinary vs salivary vs serum)

Treatment of Cushings syndrome depends on the underlying cause of excess cortisol but may perhaps include surgery, radiation, chemotherapy or the use of cortisol-inhibiting drugs. If the cause is iatrogenic, from long-term use of glucocorticoid hormones to treat another disorder, the physician will gradually reduce the dose of the externally administered steroid to the lowest dose adequate for control of that disorder. Once control is established, the dose of glucocorticoid hormones may be given on alternate days to lessen side effects for the patient.

Questions For Your Doctor About Test Results

Your doctor is in the best position to help you understand your cortisol test results. It could be helpful to ask specific questions, such as:

  • Is this cortisol test result within the reference range?
  • What does the result of this cortisol test say about my health?
  • Are you able to make a diagnosis based on this test result?
  • Do you recommend any additional tests? Why or why not?

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.

    Are The Tests Accurate

    The results of your at-home cortisol test are processed in the same labs that a doctors office uses, so theyre generally accurate.

    However, the accuracy can depend on the type of test and collection method. If you receive your results and are unsure if theyre accurate, most test providers offer to review your results with you.

    Its also a good idea to talk with a doctor after taking the test if you need more insight or guidance for next steps.

    Treatment Of Cushings Disease

    Microsurgical resection of an ACTH-secreting pituitary adenoma is the optimum treatment for Cushings disease with cure rates of 80-90 percent if a tumor is found. Surgery is most often done through a transnasal transsphenoidal approach, which will not leave a visible scar. This type of surgery may be performed, per the surgeons preference, using either a minimally invasive operating microscope or with the use of an endoscope. Partial removal of the pituitary gland may be used in patients without clearly identifiable adenomas.

    In patients to whom a remission is not obtained after surgery, the use of various medications that can inhibit cortisol production may be used, such as:

    These agents are not as effective as surgery and are considered a secondline course of treatment. In some patients who are particularly resistant to all forms of therapy, removal of the adrenal glands bilaterally may be considered.

    Post-surgery, with successful tumor removal, the production of ACTH drops below normal. This decrease is natural and temporary, and patients are prescribed a synthetic form of cortisol such as hydrocortisone or prednisone to compensate this change. Most patients can discontinue replacement therapy within six to 12 months, but others may require the use of oral steroids for several years to, possibly, their lifetime. Patients who need adrenal surgery may also require steroid replacement therapy.

    What Does Cortisol Do To My Body

    Almost all tissues in your body have glucocorticoid receptors. Because of this, cortisol can affect nearly every organ system in your body, including:

    • Integumentary system .

    More specifically, cortisol affects your body in the following ways:

    Optimum cortisol levels are necessary for life and for maintaining several bodily functions. If you have consistently high or low cortisol levels, it can have negative impacts on your overall health.

    Natural Ways To Lower Your Cortisol Levels

    Cortisol is a stress hormone the adrenal glands release. It helps your body deal with stressful situations, as your brain triggers its release through the sympathetic nervous system the fight or flight system in response to many different kinds of stress .

    While the short-term release of cortisol can help you run quickly from danger, when cortisol levels are too high for too long, this hormone can hurt you more than it helps .

    Over time, this can lead to an array of health issues such as weight gain, high blood pressure, diabetes, heart disease, insomnia or difficulty sleeping, mood irregularities, and low energy levels (

    What Happens During A Cortisol Test

    Cortisol Test for Fatigue, Weight Change & Measure Adrenal Performance/Stress

    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.

    How Much Does An At

    Most at-home testing companies dont work with insurance, but they will likely take FSA/HSA payments. Its best to reach out to your insurance company about coverage. At-home tests tend to cost less than going to the clinic since you would also be paying for a provider visit in addition to lab testing. Home cortisol test kits tend to range from about $50 to around $200 depending on the test.

    Lifestyle Changes To Lower Cortisol

    Being told my stress was out of control felt worse than when I threw caution to the wind as a teen and ended up in a Swindon Gum clinic. The treatment for that was a course of antibiotics and an awkward text message. But being forced to digest the fact that my busy AF healthy lifestyle was causing internal chaos was a bitter pill to swallow.

    How do you slow things down without feeling like youve somewhat failed at juggling a multi-hyphen career?

    To start with, I had to edit my workday and remove daily stressors. Even just eating in front of Instagram means its not relaxing, advised Kalinik. No social media and Tupperware, got it.

    But what about a protein shake as I power walk from the gym to work?

    As much as possible you need to be having meal times in an environment conducive to rest and digestion and this doesnt really happen while on the go.

    So, thats a no then.

    Kalinik also suggested a technology blackout one hour before bedtime and no relying on coffee to fuel frantic days. In fact, only one Americano a day was allowed and not downed on-the-go, on an empty stomach .

    It all sounded doable, but I also felt that I needed to understand how I ended up with such a colossal amount of cortisol in the first place.

    This resonated with me I am that woman.

    This re-shuffle led to a new routine: I embrace the LISS life and walk to work. I apply this slower pace to lunch time too and try my hardest to eat away from my desk.

    What The Results Mean

    When a technician carries out the cortisol level test between 6 a.m. and 8 a.m., the results will typically be within the range of 1020 micrograms per deciliter in a healthy person.

    A doctor will generally consider measurements outside of this range to be abnormally low or high. However, testing techniques vary between facilities. People should discuss their results with their doctor to confirm what their score may mean.

    When test results are low, it may indicate one of the following:

    • Addisons disease
    • Hypopituitarism, a condition in which the pituitary gland does not stimulate the adrenal gland to produce cortisol

    Certain medications, including phenytoin and androgen drugs, may also reduce the levels of cortisol.

    When test results indicate high cortisol levels, this may be because the person has a tumor in a part of the body that impacts the production of cortisol, such as the adrenal or pituitary gland.

    Some drugs may also elevate levels of cortisol, including estrogen-containing drugs and synthetic glucocorticoids, such as prednisone.

    Physical and emotional stress can cause raised levels of cortisol too, as can certain illnesses.

    Women may have increased levels of cortisol during pregnancy.

    How to Self

    When your cortisol levels are in the appropriate range you are able to function at peak performance. Cortisol levels can fluctuate based on what is happening in your life and your physical health, so it is important to track your cortisol levels over time. Cortisol levels can be tested using saliva or urine. The saliva method involves measuring the amount of cortisol in a sample of saliva. You place a sample of your saliva on a test strip and then place it into a sample cup. You can then use a reader to measure the amount of cortisol in your saliva. This is usually done on an hourly basis. The urine method involves collecting a urine sample and then taking it to a lab to be tested. This method is done daily because it requires less maintenance. The cortisol levels of a person can be very different based on their gender, stress levels, and the time of day that they wake up and go to sleep. If your cortisol levels are too high, then it is possible to experience insomnia and low energy. If your cortisol levels are too low, then you could experience fatigue, depression, and anxiety.

    Common Symptoms Of Elevated Stress And Sleep Deprivation:

    • Can’t 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.

    Why The Test Is Performed

    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

    What Are Normal Cortisol Levels

    Low cortisol levels and how to improve cortisol function with Dr. Alan Christianson

    The level of cortisol in your blood, urine and saliva normally peaks in the early morning and declines throughout the day, reaching its lowest level around midnight. This pattern can change if you work a night shift and sleep at different times of the day.

    For most tests that measure cortisol levels in your blood, the normal ranges are:

    • 6 a.m. to 8 a.m.: 10 to 20 micrograms per deciliter .
    • Around 4 p.m.: 3 to 10 mcg/dL.

    Normal ranges can vary from lab to lab, time to time and person to person. If you need to get a cortisol level test, your healthcare provider will interpret your results and let you know if you need to get further testing.
