                                According to the World Health Organization (WHO), the median urinary iodine concentration is the single most reliable indicator for assessing a population's iodine nutritional status. The median urinary iodine level is a statistical measure used in large-scale health surveys to determine if a population is getting enough iodine, a vital nutrient for thyroid function and overall health. It is not used to evaluate an individual's status due to day-to-day fluctuations in intake.
