The "24 Hour Urine Iodine" test offered by Doctor's Data Laboratory is a diagnostic tool used to evaluate iodine levels in the body. This test is essential for assessing thyroid gland function, immune response, and estrogen metabolism. Iodine is a crucial element required for normal thyroid function and overall health, including metabolic regulation and neurological development. Insufficient iodine can lead to issues like thyroid deficiency, weight gain, loss of energy, goiter, and impaired mental function. The test can be performed with a conventional 24-hour urine collection or after a loading dose of iodide/iodine. It measures iodine using ICP-MS, a method also used by the CDC, and assesses iodine status by evaluating the percentage of the ingested dose excreted in urine. Low excretion suggests greater bodily retention and potential need for iodine. For more detailed information, you can visit the Doctor's Data website.
