Abstract: Iodine is an indispensable trace element in the human body and its intake level is closely related to thyroid function. Iodine deficiency or iodine excess will lead to iodine-related diseases. The implementation of the universal salt iodization policy of China has achieved remarkable results, yet it is still facing the problems of iodine deficiency and iodine excess at present. Since iodine in the human body is mainly metabolized by the kidneys and excreted in urine, urinary iodine test has become an effective way to reflect the recent iodine nutrition status of the body. This article will discuss the current iodine nutrition status of the population in China, the hazards of iodine deficiency and iodine excess, as well as the clinical application of urinary iodine test.
