To read the full abstract: J Clin Endocrinol Metab. 2019;104:5765–5779.It is not clear whether retesting is needed for a healthy cotwin of a twin pair discordant for congenital hypothyroidism (CH) at the first neonatal screening. Medda et al. retrospectively analyzed a cohort of 47 twin pairs discordant for CH at the first neonatal screening. On follow-up, 7 (15%) of cotwins who were initially negatively screened then tested positi...
