The Heavy Metals panel tests for exposure to harmful heavy metals and elements such as arsenic, lead, mercury and more. Heavy metals can be found in all regions of the United States and can accumulate in air, soil, drinking and groundwater sources. Those who are immunocompromised, have impaired liver function, or have reduced antioxidants and mineral activity can benefit from this panel. Children may also benefit from this panel as they are at a higher risk of developing heavy metal toxicity.
