# Iodine, 24-Hour Urine

> This test measures the amount of iodine in your urine collected over a 24-hour period to estimate your daily iodine intake. It helps show whether your body has the right amount of iodine to support healthy thyroid function or if you have been exposed to unsafe levels. Results can help rule out dietary deficiency or excessive intake as the cause of thyroid enlargement or other symptoms. However, this test alone does not diagnose specific thyroid diseases or measure thyroid hormone levels directly.
