Quick answer
The 24-Hour Iodine Urine Test measures the amount of iodine passed in urine over a complete day. Iodine is needed to make thyroid hormones, and urine is the main route by which the body removes excess iodine. A full-day collection gives a broader picture of intake and excretion than a single spot sample, and the test is often used when iodine status or unusual iodine loss needs to be assessed.
What this test measures
Iodine is a mineral the thyroid gland uses to produce its hormones. The body does not make iodine, so it must come from food, iodized salt, and supplements. Most excess iodine leaves the body through the urine, which makes urine testing a practical way to estimate iodine status.
For a 24-hour collection, a person discards the first morning urine, then collects every urine sample for the next 24 hours, including the first morning sample of the following day. The volume is measured and a portion is sent to the laboratory, where iodine concentration is determined. The total amount excreted over the day is then calculated.
Results are usually reported as micrograms of iodine per 24 hours or as micrograms per liter along with total volume. Very low excretion can suggest insufficient iodine intake, while very high excretion can reflect excess intake or increased losses. Results are interpreted alongside diet, medications, and thyroid function tests when relevant.
