Short Synacthen Test (SST)
A normal response is a 30 minute post synacthen cortisol value of 430 nmol/L in males, 420 nmol/L in females (over 580 nmol/L in women on oral contraceptives). El-Farhan et al. Clin Endocrinol (2013) 78, 673–680.
Additional Notes: 60 minute values are about 15% higher.
NB A basal cortisol of 340 nmol/L had a 100% specificity for a normal short synacthen test, therefore SST is not needed. Sbardella et al. Clin Endocrinol (2017) 86, 177-184.
