This blood test is used to monitor thyroid problems such as iodine-induced hypothyroidism, autoimmune inflammation of the thyroid gland, and hyperthyroidism associated with excessive iodine intake.

Iodine is a health-promoting trace element naturally occuring in sea vegetables and plants. Found in high levels in the thyroid, breast, liver, lung, heart, and adrenals; iodine is essential for the body and is detected in every organ and tissue. Its primary biological role is in the production of the thyroid hormones, which have powerful influences on cardiovascular health, energy, metabolism, and weight.

One of the controversies in the field of iodine is determining how much is good for the human body. Currently, there is no generally agreed upon iodine test that can evaluate optimal iodine dosing. Some experts claim that the RDA is appropriate (about 150 mcg per day), while others claim that much larger amounts are needed and recommend supplementation.

Instructions

Fasting is not required for this test. Take all medications as prescribed.

Note

This test is not designed to determine optimal iodine status in an individual choosing to supplement with iodine; careful consideration of other thyroid function tests as well as clinical symptoms is essential.
