Iodine Urine Test
This test measures urinary iodine levels to give an indication of iodine levels in the body. Iodine is an essential trace element, important for healthy thyroid function, required to produce T3 and T4 thyroid hormones. Whether it is determining how fast your heart beats or how quickly your intestines process your food, thyroid hormones control the speed at which your body cells work. Without these hormones, the body would be unable to convert nutrients into energy.
Iodine is obtained through the diet and good sources include shellfish, dairy products and seaweed. Most people should be able to get all the iodine they need by eating a varied and balanced diet. The majority of iodine that is ingested is excreted via the urine. Measuring the amount of iodine excreted through the urine helps to determine iodine levels in the body.
Low levels of dietary iodine reduce the production of T3 and T4 thyroid hormones as without sufficient levels of iodine in the body, the thyroid is not able to function properly. Low thyroid hormone levels ultimately slow down the body’s metabolism.
