What Does The Test Measure
Testing measures the cortisol hormone in the blood, urine, or saliva. Cortisol is one of several glucocorticoid hormones that help the body control blood sugar levels, respond to stress, and regulate the immune system.
It is normal for cortisol levels to change over the day and react to various stressors. The bodys process of producing cortisol requires several steps:
- An area of the brain called the hypothalamus produces the corticotropin-releasing hormone .
- CRH travels to another part of the brain called the pituitary gland and triggers the secretion of corticotropin, also called ACTH.
- 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 and other tests like the ACTH test.
Why Is It Problematic To Have A Cortisol Problem
How Is The Test Performed
The reason this test is called a 4 tube cortisol-salivary test is that it involves spitting into 4 test tubes at different times of the day. Your saliva contains a lot of information regarding your levels of cortisol. You should do this at different moments of the day to ensure an accurate reading.
For example, the first collection time is in the morning right after you woke up. This is best done around 8 AM. The second collection time is at noon. In the evening or around 4 PM you should collect another sample. Finally, the last sample should be collected at midnight, preferably between 11 PM and 11:30 PM.
Your cortisol levels vary depending on various factors. Collecting samples at different moments of the day offers a more accurate reading. The timing is crucial, so you will be responsible to set alarms throughout the day, so you can collect the samples at the right moment.
Keep in mind that you might need to interrupt taking sublingual hormones or topical hormones at least 2-3 days before collecting the saliva samples. These hormones might interfere with the end result. Your doctor can tell you more information about this, so don’t be afraid to ask what you’re allowed and not allowed to do before taking a 4-tube cortisol-salivary test.

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
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 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. Talk with your doctors office and health insurance provider for detailed information about the costs of cortisol testing.
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 if you are uninsured.
A cortisol test costs $69 from Testing.com.

Biochemical Workup Of The Different Patient Groups Before Measurement Of Salivary Cortisol
All patients tested for adrenal insufficiency developed symptomatic hypoglycemia but did not experience any severe side effects in response to insulin administration during the ITT. Thirty-two patients responded normally to hypoglycemia , whereas 30 patients had a subnormal response . In detail, adrenal insufficient patients had a mean peak serum cortisol of 266.5±30.4nmol/l to insulin-induced hypoglycemia, whereas adrenal sufficient patients demonstrated a mean peak serum cortisol of 586.7±17.9nmol/l. Hypercortisolemic patients had a mean dexamethasone-suppressed serum cortisol of 480.6±35.2nmol/l. Furthermore, mean plasma ACTH was 5.3±0.6pg/ml in patients with cortisol-producing adrenal masses and 66.8±14.1pg/ml in patients with ACTH-dependent Cushing’s syndrome. On the contrary, patients with noncortisol-producing adrenal tumors had a mean serum cortisol of 43.6±4.9nmol/l after dexamethasone.

What Are Normal Values For Cortisol Levels
There are a few reference values for salivary cortisol that help doctors diagnose adrenal insufficiency or other forms of problems with your adrenal glands. Your cortisol levels are usually the highest early in the morning and they drop throughout the day.
- Between 0.025 – 0.600 ug/dl in the morning
- Between 0.010 – 0.330 ug/dl in the afternoon
- Between 0.010 – 0.200 ug/dl in the evening
- Between 0.010 – 0.090 ug/dl at night
These are the standard values for salivary cortisol for children and adults. Anything higher or lower would qualify you for adrenal insufficiency. Once you get the results, you can compare them against these values as well as ask for assistance from your primary healthcare provider.
Functions Influenced By Cortisol Levels
Abnormal adrenal function can alter the ability of cells to produce energy for the activities of daily life. People who have a hard time rising in the morning, or who suffer from low energy throughout the day, often have abnormal adrenal rhythms and poor blood sugar regulation.
The maintenance of a stable blood sugar level depends on food choice, lifestyle, adrenal function, and insulin activity. The Adrenal Stress Index panel measures stress hormones and insulin, to help clarify the causes of fatigue, cravings, and obesity.
Immune System Function
Various immune cells cycle in and out of the spleen and bone marrow. The immune system trafficking follows the cortisol cycle. If the cycle is disrupted, especially at night, then the immune system is adversely affected. Short and long-term stress is known to suppress the immune response in the lungs, throat, urinary tract, and intestines. With lowered levels of mucosal antibodies , our resistance to infection is reduced and allergic reactions may increase.
Human skin regenerates mostly during the night. With higher night cortisol values, less skin regeneration takes place. Therefore a normal cortisol rhythm is essential for optimal skin health.
Muscle and Joint Function
Abnormal adrenal rhythms are known to compromise tissue healing. Reduced tissue repair and increased tissue breakdown can lead to muscle and joint wasting with chronic pain.

When Should I Get This Test
Your doctor may recommend cortisol testing if they think you have a condition affecting your cortisol levels.
Doctors may initiate cortisol testing if you have a health problem unusual for people your age, such as young adults with hypertension or osteoporosis. They may also recommend cortisol testing if you have a severe health condition affecting 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 other diseases most often cause these symptoms. 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.
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 test be conducted at a specific time, depending on the tests purpose.
Blood samples for cortisol tests are often collected early in the morning when the cortisol level 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 home. When testing for high cortisol, your doctor may instruct you to collect a saliva sample late at night while at home.
For a cortisol urine test, you will be provided with containers and detailed instructions on collecting all the urine you produce in 24 hours, after which you will return it to a lab. For convenience, you may choose a 24-hour period when you expect to be at home.

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.
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.

Advanced Adrenal Stress Test
Stress Could Be A Cause of Your Patients Illness
Precision Point Diagnostics Adrenal Stress Test measures 4-point cortisol, DHEA , and secretory IgA in a convenient saliva specimen. Cortisol has been found unbound in saliva samples, indicating a strong correlation to cortisol concentrations in serum.1 Checking patients for low or high cortisol over the course of the day is essential to address fatigue, insomnia, thyroid disorders, or weight gain. However, adrenal function, officially known as the hypothalamic-pituitary-adrenal axis, impacts many other systems and symptoms in the body. Low cortisol levels may cause blood pressure dysregulation, irritability, hypoglycemia, anxiety, depression, and difficulty coping with lifes challenges.
Knowing exactly what your patients cortisol levels are throughout the day helps you customize an effective treatment to bring the cortisol curve- or circadian rhythm- back into balance. Findings from the Adrenal Stress Test can help to balance DHEA, a precursor hormone for estrogen and testosterone. The test also gives information about salivary sIgA, a critical player that prevents infection at the mucosal lining.
