To determine whether a random postoperative day-3 cortisol value of 10 μg/dL or greater is predictive of adrenal sufficiency 3 to 10 weeks after transsphenoidal surgery (TSS) and during long-term clinical follow-up. ⋯ In the appropriate clinical context, a postoperative day-3 cortisol value of 10 μg/dL or greater accurately predicts the integrity of the HPA axis. The final decision regarding corticosteroid replacement should be personalized, considering the postoperative day-3 cortisol level, the clinical context in which the measurement was obtained, and any evidence of concomitant pituitary dysfunction in the perioperative period.
