Each test included in ZRT’s element panels has been selected for its value in providing clinical insight. The comprehensive profile reveals exposure to the four heavy metals labeled most hazardous by the CDC, along with essential elements that interact directly with these heavy metals in the body. Our thyroid profile highlights the toxic and nutritional elements that play a critical role in thyroid function.


Element concentrations in blood and urine may indicate completely different types of exposure and toxicity, even when analyzing the same element. ZRT tests the most meaningful sample types for each element, and avoids testing elements in sample types that may be misleading or have no clinical relevance.


ZRT offers insightful and personalized comments on every report – correlating levels and symptoms to deliver real understanding. These comments highlight the role various elements play in health, and how deficiencies and excesses can lead to system dysfunction.
