Morning cortisol has wide biological variation, and many patients with results below this threshold will have normal adrenal function. Lower results, particularly below 100\u2013150 nmol\/L, make adrenal insufficiency more likely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not use serum cortisol as a screening test for adrenal insufficiency in pregnancy or in patients taking an oestrogen-containing combined oral contraceptive pill.
