What is the purpose of this test?
Order this Iodine Blood Test, which measures iodine levels in the blood to screen for a deficiency or excess. Iodine is an elemental mineral that plays a crucial role in the human body by aiding in the production of thyroid hormones, including thyroxine (T4) and triiodothyronine (T3). These hormones are responsible for regulating a variety of important biochemical reactions, such as protein synthesis. In addition, thyroid hormones are vital for maintaining a healthy metabolic rate. Several dietary sources of iodine include fish, seafood, and eggs. An additional source is table salt, which is fortified with iodine. It is essential to ensure that you consume adequate amounts of iodine to support the healthy functioning of the thyroid gland and overall good health.
Certain groups of people are at a higher risk of iodine deficiencies, such as:
- Individuals who do not consume iodized salt or live in areas with low iodine sources
- Pregnant women
- Vegans
- Individuals who consume little to no dairy products, seafood, and eggs
What conditions are associated with abnormal iodine levels?
Iodine deficiency is the leading cause of brain damage worldwide, and pregnant women who lack iodine may experience miscarriage, stillbirth, low birth weight, and congenital abnormalities like cretinism. Children who lack iodine can suffer from physical and mental growth impairments, while both children and adults may develop goiter, an enlarged thyroid. Although most people can handle large amounts of iodine, some individuals may experience hyperthyroidism or hypothyroidism from excessive intake.
When should I order an Iodine Blood Test?

- Choking
- Difficulty swallowing
- Trouble breathing
- Infertility
