Iodine SPOT

Back to list

The measurement of urinary iodine (IU) provides an accurate approximation of dietary iodine intake. The majority of iodine that is ingested (90%) is excreted via the urine. When there is adequate amounts of iodine in the body to support various bodily systems, the body offsets excess by excreting it in the urine.  UI measurements provide a biological indicator of Iodine deficiency disorders by determining whether the body has sufficient levels.

Iodine's main action is involved in thyroid function. Due to the numerous actions carried out by the thyroid, the implications of iodine deficiency are significant.  The major hormone secreted by the thyroid is thyroxine, also called T4 because it contains 4 iodine atoms. To exert its effects, T4 is converted to T3 by the removal of one iodine atom. This occurs mainly in the liver and other tissues where T3 acts, such as the brain.  Other actions include the formation and integrity of normal breast tissue, foetal brain development and function, and anti-microbial effects.

Companion Tests:

  • Thyroid Hormone Profile
  • Baseline Hormone Profile
  • Adrenal Hormone Profile

The results of the urinary iodine test may support or be supported by additional BeFunctional testing. Given the importance of Iodine for thyroid function, combining Urinary Iodine with the Thyroid Hormone Profile is important to ensure a comprehensive assessment of thyroid function. An underactive thyroid is also common in menopausal and post-menopausal women.

A Baseline Hormone Profile may be required to provide additional information in terms of identifying hormonal imbalance in menopausal and post-menopausal women.

The Adrenal Hormone Profile, which measure Cortisol and DHEA-S over a 24-hour period, may also be a useful test to consider as physical, mental and environmental stressors can inhibit the conversion of T4 to T3, this decreasing the amount of active thyroid hormone available to the cells.
