GH1 and pituitary gland disorder: A more recent research evaluated the best GH peak cutoff to reduce overdiagnosis of GHD in overweight and obese patients during GST at FD (1 mg or 1.5 mg if body weight was > 90 kg) or WB dose (0.03 mg/kg) using ITT as gold standard [42]; the study included 28 adult patients with hypothalamic–pituitary disease and 14 healthy controls matched for age, sex, BMI and estrogen status, and proposed a GH peak cutoff of 1.0 μg/L for FD (92% sensitivity and 100% specificity) and 2.0 μg/L for WB dose (96% sensitivity and 100% specificity).
