Cortisol is a hormone produced by the adrenal glands. If cortisol levels are too high or too low, this organ can be dysfunctional or have real disease. In particular, testing blood cortisol levels in the diagnosis of Cushing's syndrome and adrenal insufficiency is the most common goal in order to make timely and appropriate adjustments for the patient.

Cortisol testing helps diagnose diseases in advance, especially Cushing's syndrome or kidney failure. This test helps doctors make an accurate diagnosis and prescribe appropriate treatment regimens for patients.

Cortisol is an important component that helps the body control stress and fear. Excessive increases or decreases in cortisol over a long period of time can potentially cause pathological conditions.

Cortisol is an antidepressant hormone secreted in the adrenal cortex. The concentration of cortisol in the body is highest in the morning and lowest at night. A cortisol test is used to assess the state of decreased or increased cortisol, thereby helping to diagnose Cushing's disease, Addison's disease or some diseases related to the adrenal cortex.
