Short Synacthen Test (SST) Indications The purpose of the test is to diagnose adrenal insufficiency. Under normal circumstances, pituitary ACTH stimulates the secretion of cortisol from the adrenal gland; Synacthen (a synthetic ACTH called tetracosactrin) has a similar effect. However, in patients with adrenal

A baseline blood draw for cortisol is done and then synacthen is given into the blood stream or the muscle. 30 minutes later a second blood draw for cortisol is done. The Synacthen test is unreliable if performed within 4 weeks of pituitary surgery as ACTH deficiency may not have been sufficiently prolonged to result in adrenal atrophy. An 8 – 9 am plasma ACTH and cortisol can be informative in these situations.

Since 1988, when a retrospective study of patients attending this unit was published, we have advocated the use of the short synacthen test (SST) as the

Synacthen test

SST is also known as the cosyntropin test or ACTH test. Synacthen is a trade name for tetracosactrin, a synthetic peptide that comprises the first 24 (out of 39) amino acids of the endogenous ACTH peptide. In an SST, blood for baseline plasma cortisol and ACTH is first collected.

Synacthen test

If plasma cortisol increases by >200 nmol/L (70 micrograms/L), i.e. if the value 30 minutes after injection is >500 nmol/L (180 micrograms/L), adrenocortical function is regarded as normal. If there is clinical suspicion of adrenal insufficiency, a short Synacthen test is a definitive test to diagnose or exclude the disease. If patients are on steroids that can potentially cross-react on cortisol assays, these should be withheld for 24–48 hours prior to the short Synacthen test. En bioanalytiker tager en blodprøve før og 30 minutter efter, du har fået Synacthen. Undersøgelsen varer i alt cirka 45 minutter, og du kan tage hjem umiddelbart efter.
