The Heavy Metals panel examines heavy metal toxicity to 20 of the most common heavy metals, which can be found in the environment, air, water sources, and common consumer products. Heavy metal toxicity can contribute to a total toxic burden and cause inflammatory symptoms including neurological and cognitive (brain) dysfunction, metabolic problems, digestive complaints, impaired detoxification, and more.

Environmental toxins, technically called toxicants, are substances produced endogenously from the human body and which, when absorbed, inhaled, or ingested, can cause acute or chronic toxic overload, which may manifest in a variety of biological organ, tissue, and cellular-level systems.
