ADRENOCORTICOTROPIC HORMONE (ACTH)

Description

The test measures the level of ACTH in the blood and is crucial for evaluating the health of the adrenal and pituitary glands. This test is used to diagnose conditions such as Cushing’s syndrome (elevated cortisol), Addison’s disease (low cortisol) and pituitary disorders. By assessing ACTH levels, the test helps pinpoint whether adrenal dysfunction is caused by issues in the adrenal glands themselves or by the pituitary’s regulation of ACTH.
