ZRT Comprehensive Toxic & Essential Elements Profile

Environmental pollutants are all around us - in the air we breathe, in the water we drink, in the food we eat and in materials we touch. This profile measures toxic heavy metals and reveals levels of certain nutritional elements.

These elements directly or indirectly impact thyroid hormone synthesis and intracellular conversion of T4 to T3. While lead, arsenic, mercury, and cadmium are known biological toxins, iodine, bromine 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 overall body burden of toxic elements and is an indicator of excessive or inadequate intake or supplementation of iodine and selenium.

Heavy Metals

These pollutants can significantly increase our risk of developing conditions like dementia, infertility, diabetes, and cancer. They are also known to cause damage to the liver, kidneys, and brain, as well as the cardiovascular, nervous and endocrine systems.

In excess, and when persistent, they can affect the synthesis and actions of hormones essential for managing our general health.

This test measures for these hazardous heavy metals: lead, mercury, arsenic and cadmium.

Essential Elements

Overall, nutritional elements are only healthy when they are within optimal ranges. Levels too low or too high can have detrimental effects on health. Therefore, it's important to know if these are outside their optimal ranges.

This test measures for these essential elements, which can be hazardous in too high amounts: zinc, copper, magnesium, selenium, bromine, lithium and iodine.

People who will especially benefit from elements testing include those who:

  • Smoke
  • Are exposed to heavy metals through work, hobbies or dentistry
  • Live in older homes or areas where metals may be present in drinking water
  • Have thyroid-related health issues
  • Are breastfeeding
  • Have health issues that could result from nutritional deficiencies or imbalances of essential elements

This comprehensive profile includes:

Blood Spot Tests: Zinc, Copper, Magnesium, Cadmium, Lead, Mercury and Selenium

Dried Urine Tests: Iodine, Bromine, Selenium, Lithium, Arsenic, Cadmium, Mercury, Creatinine
