The Iodine Profile is a urine-based test that measures iodine excretion using a dried urine sample collected on specialised filter paper. As more than 90 percent of iodine intake is excreted in urine, urinary iodine provides a practical marker for assessing iodine status without requiring a full 24-hour urine collection.
This test may be clinically useful when practitioners want to evaluate iodine intake in relation to thyroid health and hormonal balance. Measuring iodine excretion can help place symptoms such as fatigue, temperature sensitivity or changes in hair and skin into nutritional context, particularly where iodine intake or exposure is uncertain.
Practitioners typically interpret results alongside dietary intake, supplement use, thyroid-related blood tests and clinical history. Findings are reviewed in context when discussing iodine status with clients.
