Iodine

This urine test measures iodine levels, an essential mineral required for thyroid hormone production. Iodine deficiency impairs thyroid function, potentially causing goiter (thyroid enlargement) and hypothyroidism. This test assesses whether you're consuming adequate dietary iodine from sources like iodized salt, seafood, and dairy. Iodine status is particularly important for pregnant women and developing children, as deficiency can affect brain development and growth.
