POMC and chronic primary adrenal insufficiency: At the time his glucose level was 12.8 mmol/L, a random cortisol level was 6 nmol/L (normal 68 nmol/L–327 nmol/L) and simultaneous plasma adrenocorticotropic hormone (ACTH) was 253 pmol/L (normal 1.6–13.9 pmol/L), suggestive of primary hypoadrenalism, and therefore an ACTH stimulation test was not deemed necessary.
