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...
