Relation of cortisol and GH to age in 63 samples collected from 56 paediatric subjects investigated for suspected hypoglycaemia. (A) Cortisol in hypoglycaemic subjects (glucose <2.5 mmol/l). The three samples with cortisol <500 nmol/l in infants aged 8–10 months were from patients with persistent hyperinsulinism or reactive hypoglycaemia respectively (see text). (B) GH in hypoglycaemic subjects. The two samples with GH <10 mU/l in infants aged 8–10 months were from patients with persistent hyperinsulinism or reactive hypoglycaemia respectively (see text). (C) Cortisol in non-hypoglycaemic subjects (glucose ⩾2.5 mmol/l). (D) GH in non-hypoglycaemic subjects.
