Heavy Metals & Essential Elements Tests

Testing for heavy metals and essential elements is crucial because getting too much or too little of these elements can have serious effects on overall health. This type of testing is especially important for individuals who smoke, use private well water or live in homes with aging pipes, are concerned about heavy metals in foods like rice, seafood, and vegetables, have mercury dental fillings, live in older houses or near industrial areas, or struggle with thyroid-related health issues. ZRT’s heavy metals and essential elements testing provides the most accurate results by using ICP-MS, the gold standard for element analysis, offering unmatched sensitivity and precision down to parts-per-trillion. Since different elements affect the body in different ways, the right sample type matters, which is why ZRT uses either urine or dried blood spot for testing. For example, urinary cadmium is the best indicator of accumulated exposure, while blood spot reflects only recent exposure, and urine is the only accurate medium for arsenic. Both collection methods are simple and patient-friendly—dried urine allows discreet at-home testing without the inconvenience of 24-hour jug collection, while dried blood spot testing is quick, nearly painless, and can be done privately at home without visiting a phlebotomist. Together, these options ensure that you get accurate, convenient, and reliable insights into your body’s balance of essential and toxic elements so you can take control of your health with confidence.
