3.9. Newborn screening TSH values less than 15 mIU/L are not associated with long-term hypothyroidism or cognitive impairment

R West , J Hong , JGB Derraik , D Webster , NL Heather , PL Hofman

J Clin Endocrinol Metab. 2020;105:dgaa415. doi: 10.1210/clinem/dgaa415.The optimal cut-off for neonatal screening has long been a matter of debate. The optimal balance between optimal detection of cases and increase of false positive patients is difficult to define. Also, in the most recent guidelines for congenital hypothyroidism (see previous paper in this chapter 3.7), no precise cut-off...

J Clin Endocrinol Metab. 2021;106:e1231–e1239. doi: 10.1210/clinem/dgaa901.The results of this study are a robust argument to implement neonatal screening for central congenital hypothyroidism (CCH) worldwide. Only few countries, such as the Netherlands, screen for CCH. Neurodevelopmental outcome data are scarce for CCH compared to primary congenital hypothyroidism (PCH) not only becau...
