Measures of iodine excess

  • overall iodine levels cannot be reliably measured in individuals given the considerable day-to-day variation in iodine intake (1)
    • median urinary iodine concentrations (UIC)
      • have been widely used as a biomarker of population iodine intake
      • levels >300 µg/l considered excessive in children and adults and levels >500 µg/l considered excessive in pregnant women (1)
