A Cortisol Test, also known as Serum Cortisol Test, Plasma Cortisol Test, or Blood Cortisol Test, measures the level of cortisol in the blood. Cortisol is a hormone produced by the adrenal glands, playing a critical role in regulating metabolism, blood pressure, immune response, and stress. This test is commonly used to diagnose conditions that affect cortisol production, such as Cushing's syndrome or Addison's disease. By assessing cortisol levels, healthcare providers can better understand how well the adrenal glands are functioning.
The Cortisol Test is suitable for individuals who may have symptoms suggesting an imbalance in cortisol levels. This includes people experiencing unexplained weight gain, high blood pressure, fatigue, muscle weakness, or excessive hair growth, which can indicate high cortisol levels (Cushing's syndrome). On the other hand, those showing signs like chronic fatigue, weight loss, low blood pressure, or darkening of the skin may have low cortisol levels, possibly pointing to Addison's disease. It is also recommended for patients with chronic stress or those undergoing evaluations for conditions involving the hypothalamic-pituitary-adrenal (HPA) axis.
The Cortisol Test can be performed whenever a healthcare provider deems it necessary to assess adrenal function. Since cortisol levels fluctuate throughout the day, with peak levels typically occurring in the early morning and the lowest levels at night, the test is often done in the morning between 6 a.m. and 8 a.m. For more comprehensive analysis, doctors may request multiple tests throughout the day to observe fluctuations and assess the diurnal pattern of cortisol secretion. Patients may also undergo this test before or after specific stimulation or suppression tests, such as the ACTH stimulation test or dexamethasone suppression test.
The procedure for a Cortisol Test involves a simple blood draw. A healthcare professional will clean the area, usually the inside of the elbow, and insert a needle to collect a blood sample. This sample is sent to a laboratory for analysis to measure the cortisol level. The blood draw itself takes only a few minutes, and the patient can resume normal activities shortly afterward. Results are typically available within a few days, depending on the lab processing time.
A Cortisol Test is most often associated with diagnosing and managing conditions such as Cushing's syndrome, where excess cortisol production leads to symptoms like weight gain, muscle weakness, and high blood pressure. It is also essential for diagnosing Addison's disease, where insufficient cortisol production causes symptoms such as chronic fatigue, low blood pressure, and weight loss. Additionally, the test is helpful in evaluating the effects of chronic stress on the body, as prolonged high levels of cortisol can contribute to health issues such as cardiovascular disease, anxiety, and metabolic disorders. Conditions affecting the pituitary gland or adrenal glands may also be monitored through cortisol testing.
The Cortisol Test is considered very safe, with minimal risks involved. The most common risk is slight discomfort or bruising at the site of the blood draw. Some individuals may experience lightheadedness or fainting, but these effects are rare and usually short-lived. In very uncommon cases, infection or hematoma may occur at the needle insertion site. These potential risks can be minimized when the blood draw is performed by a skilled healthcare professional.
Preparation for a Cortisol Test is straightforward. Patients are often advised to avoid intense physical activity and stress the day before the test, as these can impact cortisol levels. Some medications, such as corticosteroids or birth control pills, may need to be paused or adjusted before the test to prevent interference with the results. It is essential to inform the healthcare provider about any medications being taken. Patients may also be asked to fast for a few hours before the test, although specific instructions will vary based on the doctor’s guidelines.
Other tests related to the Cortisol Test include the ACTH (Adrenocorticotropic Hormone) Stimulation Test, which helps evaluate adrenal gland function by measuring the response of cortisol levels after an ACTH injection. The Dexamethasone Suppression Test is another related exam that checks how cortisol production responds to a synthetic steroid called dexamethasone, helping diagnose conditions like Cushing's syndrome. Additionally, 24-hour urinary free cortisol tests and salivary cortisol tests can be used to monitor cortisol levels over time and provide more comprehensive data about daily cortisol fluctuations.
