Newborn screening (NBS) for congenital hypothyroidism (CH) facilitates early diagnosis and treatment and prevents permanent intellectual disability. Sadly, 50 years after the first introduction of NBS for CH, only 29.6% of newborns worldwide are screened. Africa and Asia, the continents with the highest birth rates, have very limited screening coverage. Most NBS programs measure TSH in a dried-blood spot taken from a heel-prick on a filter paper after 24 to 72 h of life. Implementing national NBS programs is logistically complex and expensive, requiring parental consent, specialized laboratories, and excellent infrastructure. In limited-resource settings, introducing such a complex program is often impossible. We propose universal decentralized cord blood TSH screening, offered as routine delivery care for all newborns in limited-resource settings. TSH measurement may be performed by local laboratories using widely available, inexpensive radioimmunoassay kits, with the report available within a few hours. Since the TSH report would be available before discharge, suitable clinical decision making would be possible, with a minimal need for recall, thus minimizing the parental, medical, and financial burden and improving developmental outcomes. The most important requirement is to change to a grassroots approach, with the education of obstetricians and pediatricians worldwide to perform routine cord blood TSH and make sure the TSH result is available before the baby is discharged.
