Urinary iodine is the most widely used indicator of recent iodine intake and iodine status. When the body has enough iodine, it excretes the excess through the urine. Therefore, measuring the amount of iodine in the urine can provide information about recent dietary intake and overall iodine status. The other options (A, B, and C) are not reliable indicators of iodine status or recent intake. The goiter rate indicates a long-term iodine deficiency, serum thyroglobulin is affected by many factors besides iodine intake, and serum thyroid-stimulating hormone can be affected by various factors other than iodine intake.
