Urinary iodine (I)

Normal adults contain 20 to 50 micrograms of iodine. Iodine enters the body and can be taken along with food, water, salt and other means. 70% to 80% of the iodine absorbed mainly from the intestine is concentrated in the thyroid gland, which is mainly discharged through the urine. Iodine is an element that makes up thyroxine. It exerts biochemical effects through thyroxine (T4) and triiodothyronine (T3). Iodine-deficient diseases include endemic goiter and endemic cretinism. However, excessive intake of iodine can also cause illness, such as hyperiodative endemic goiter. Detection of urinary iodine is an important and simple indicator of iodine deficiency.
