ZRT Toxic & Essential Elements - Dried Urine

Analyzing elements can provide insight into why you may not synthesize or convert thyroid hormones and can help determine the cause of thyroid related symptoms. The thyroid gland regulates cellular energy metabolism, as well as controls heart rate and protein synthesis for proper growth and development. 

These elements directly or indirectly impact thyroid hormone synthesis and intracellular conversion of T4 to T3. While bromine, arsenic, mercury, and cadmium are known biological toxins, iodine and selenium can potentially be toxic also if dietary intake, including excessive supplementation, is too high. Testing for these elements in urine provides an excellent assessment of the overall body burden of toxic elements and is an indicator of excessive or inadequate intake or supplementation of iodine and selenium.

This Elements Profile measures: Iodine, Lithium, Bromine, Cadmium, Selenium, Arsenic, Creatinine, and Mercury.

This test does NOT include: zinc, copper, magnesium, or lead. See our other Elements tests for those (below).

Sample only derived from dried urine (not blood spot).
