The Iodine Blood Test is useful in the diagnosis of iodine deficiency or excess, iodine-induced hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid), and autoimmune thyroid diseases such as Graves' disease and Hashimoto's thyroiditis, as well as monitoring exposure to iodine.

Iodine is a mineral listed by the World Health Organization (WHO) as one of the most important micronutrients. Adequate amounts are essential for proper thyroid function and critical during pregnancy for healthy development of the fetus. The body’s primary source of iodine is food; seafood, dairy products and whole grains tend to be good sources of the mineral in the U.S. Iodized salt is also a common source. Recommended daily intake varies by agency, but the WHO, International Council for the Control of Iodine Deficiency Disorders, and UNICEF recommend the following amounts:

  • Up to 7 years old: 90 micrograms (mcg)

  • 7-12 years old: 120 mcg

  • 12 years and older: 150 mcg

  • Pregnant/breastfeeding women: 200 mcg

Throughout the world, iodine deficiency is the most common cause of brain damage. Deficiency in pregnant women can result in miscarriage or stillbirth, low birth weight, and congenital abnormalities such as cretinism, a severe condition characterized by stunted growth and mental retardation. In children, iodine deficiency can impair physical and mental growth and development, and in both children and adults, goiter (enlarged thyroid) ran result.

High iodine intake may or may not result in symptoms because people vary widely in their tolerance of excess amounts. Most people who haven’t been iodine deficient can handle large amounts without problems, but some individuals may experience conditions such as hyperthyroidism or hypothyroidism.

An Iodine Test is also known as Iodine Serum. No fasting is required prior to the test, and results will be available within two to three days. A prior doctor’s visit is not required to order this test. Patients also do not need insurance.
