Serum iodine

Serum iodine refers to the amount of iodine present in the bloodstream. Iodine is an essential nutrient that our bodies need to produce thyroid hormones, which regulate metabolism, growth, and development. Testing serum iodine levels can help assess whether a person has enough iodine. Low levels can lead to health issues like goiter and thyroid problems, while excessively high levels can also be harmful. A balanced diet, including sources like fish, dairy, and iodized salt, usually provides sufficient iodine for most people. Monitoring serum iodine is important for overall health, especially in regions where iodine deficiency is common.
