Aktivaatoritest

Aktivaatoritest, also known as an activator test, is a diagnostic procedure used to assess the functionality of the hypothalamic-pituitary-adrenal (HPA) axis, which is responsible for the body's stress response. This axis consists of the hypothalamus, pituitary gland, and adrenal glands. The aktivaatoritest is particularly useful in evaluating conditions such as adrenal insufficiency, Cushing's syndrome, and other disorders affecting the HPA axis.

The test involves administering a synthetic corticotropin-releasing hormone (CRH) or a synthetic adrenocorticotropic hormone (ACTH) to stimulate the release of cortisol from the adrenal glands. Blood samples are then collected at specific intervals to measure cortisol levels. The results are analyzed to determine the responsiveness of the adrenal glands to the administered hormone.

There are two main types of aktivaatoritests: the CRH test and the ACTH test. The CRH test is typically used to evaluate primary adrenal insufficiency, while the ACTH test is used to assess secondary adrenal insufficiency. Both tests provide valuable information about the function of the HPA axis and help in diagnosing and managing related disorders.

The aktivaatoritest is a valuable tool in clinical practice, offering insights into the body's stress response and adrenal function. It is often used in conjunction with other diagnostic tests and clinical evaluations to provide a comprehensive assessment of the HPA axis.
