    Iodine Testing Priorities: Urine, Blood, and the Limits of Each Test

    Iodine testing can be confusing because urine, blood, and thyroid markers answer different questions. This article explains when a 24-hour urinary iodine test offers the most useful view, why serum iodine mainly helps assess excess exposure, and how thyroglobulin, thyroid labs, diet, supplements, pregnancy, and medications fit together. The goal is not one perfect number, but a coherent clinical interpretation for each individual patient thoughtfully.
