urine iodine
Urinary iodine is a well-accepted, cost-efficient and easily obtainable. indicator for iodine status. Since the majority of iodine absorbed by the. body is excreted in the urine (4), it is considered a sensitive marker of. current iodine intake and can reflect recent changes in iodine status (5). However, this indicator does not provide direct information about thyroid. function (6).
