The insulin stress test (IST) (or insulin tolerance test, ITT) has traditionally been the 'gold standard' test to assess the adequacy of the ACTH–adrenal axis.

An insulin tolerance test (ITT) is a medical diagnostic procedure during which insulin is injected into a patient's vein, after which blood glucose is measured ...

The insulin tolerance test (ITT) is widely held as the “gold standard” investigation for assessing ACTH and cortisol reserve.

ACTH and GH are both released as part of the stress mechanism triggered by insulin induced hypoglycaemia. Indications. 1. Diagnosis of secondary adrenal failure ...

While a peak cortisol value of >18 microg/dl is usually interpreted as a sufficient response to the ITT, the plasma ACTH response has not yet been standardized.

The insulin tolerance test will assess how much ACTH, cortisol and growth hormone is produced when your body is under stress. This 'stress' will be induced ...

In clinical practice, low-dose adrenocorticotrophic hormone (ACTH) stimulation test is a sensitive, safe and easily applicable alternative to ITT. Although it ...

ACTH levels may also be measured. If you suspect severe cortisol and/or GH deficiency and still want to proceed with the test, consider using a lower insulin ...
