To read the full abstract: J Clin Endocrinol Metab. 2018;103:3720–28.This nationwide prospective surveillance study aimed to estimate the performance of the current UK recommended TSH threshold (10 mU/L on day 5 after birth) for newborn blood spot screening compared to lower thresholds: 8 mU/L and 6 mU/L. Over a 12-month period, the authors included all patients with positive TSH ba...
