The clinical presentation of adrenal insufficiency is variable, depending on whether the onset is acute, leading to adrenal crisis, or chronic, with symptoms that are more insidious and vague. ACTH Stimulation Test (Cosyntropin) Purpose: Evaluation of possible primary or secondary adrenal insufficiency, as well as disorders of adrenal steroid biosynthesis, such as congenital adrenal hyperplasia (CAH). Adrenal insufficiency can be difficult to diagnose. You have two adrenal glands. Adrenal insufficiency, a potentially fatal condition in the case of adrenal crisis, is defined as hypofunction of the adrenal gland with decreased or absent hormone secretion. They work with the hypothalamus and pituitary glands in the brain. Cortisol helps break down fats, proteins, and carbohydrates in your body. Therefore, the diagnosis of adrenal insufficiency depends upon a critical level of clinical suspicion. Adrenal Insufficiency is quite complicated and can be caused by about 50 different conditions. Serum cortisol: Less than 20 mcg/dL in severe stress or after ACTH stimulation is indicative of adrenal insufficiency. Adrenal Insufficiency (Addison's Disease) Adrenal insufficiency occurs when the adrenal glands don’t make enough of the hormone cortisol. 1,2. Therefore, patients may require glucocorticoid replacement therapy after chronic use of corticosteroids in periods of stress, such as trauma, surgery, or acute illness, until full recovery of adrenal function. These include cortisol, sometimes called the “stress hormone,” which is essential for life. They are located just above the kidneys. Diagnosis. It should be drawn between 8 and 9am. Addison disease and Adrenal insufficiency are hormonal or endocrine disorders arising from the body’s inability to produce enough aldosterone and adrenal hormones. This test measures the level of cortisol in your blood before and after an injection of synthetic ACTH. Adrenal insufficiency, including Addison’s disease, is a disorder that occurs when the adrenal glands don’t make enough of certain hormones. Adrenal Insufficiency, Addison Disease, And Laboratory Tests. It can be classified as primary, secondary, or tertiary. You may be given this test if doctors think you may have adrenal insufficiency as a result of pituitary disease (secondary adrenal insufficiency). process involving the adrenal glands or a pituitary adenoma compromising normal pituitary function) LAB TESTING FOR ADRENAL INSUFFICIENCY Tests to evaluate the HPA axis: The morning serum cortisol checks baseline adrenal cortisol production. However, the absence of laboratory abnormalities does not exclude the diagnosis of adrenal crisis. Your doctor will begin by asking about your medical history and about any obvious symptoms you are experiencing. The goal of laboratory testing is to document a low cortisol level and determine whether the adrenal insufficiency is primary or secondary, as outlined in Figure 1. ACTH signals your adrenal glands to produce cortisol. Adrenal insufficiency is a serious, potentially life-threatening side effect of corticosteroid use. Insulin-induced hypoglycemia test. ACTH is a hormone produced in the anterior pituitary gland that stimulates the adrenal glands to release cortisol, dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S), and aldosterone. The test evaluates pituitary corticotropin, (ACTH) production.
