Influence of Iodine Deficiency and Excess on Thyroid Function Tests

Thyroid Function Testing

Part of the book series: Thyroid Function Testing ((ENDO,volume 28))

Abstract

Iodine is an essential component of the thyroid hormones, and adequate iodine intake is necessary for normal thyroid function. The iodine intake of populations is assessed by measuring urinary iodine concentration (UIC) in a spot urine sample [1]. The recommendations for daily iodine intake and the recommended levels for optimal iodine nutrition by age and population group are shown in Table 3.1 [1, 2]. The epidemiological criteria for classifying the degree of iodine status in a population based on median or range of UIC or both UIC cutoffs are listed in Table 3.2.
