Background: The World Health Organization (WHO) has recommended measurement of neonatal thyroid-stimulating hormone (TSH) as a marker of population iodine status. A population is considered iodine sufficient when <3% of neonatal blood samples collected 3-4 days after birth have TSH concentrations >5 mIU/L. However, changes in technology and clinical practices have opened the WHO criteria to various interpretations.
