A heavy metals profile is a test used to detect dangerous levels of poisonous heavy metals including arsenic, cadmium, mercury or lead, which can build up in the body over time. This test is especially important for people who work with heavy metals regularly, including industrial and laboratory workers or artists. Patients who suspect that they may have been exposed to heavy metals may also need to have this test performed.

Patients who have had heavy metal exposure may have no symptoms or symptoms that vary according to the type and severity of the exposure. Some signs of metal poisoning include pain in the abdomen, vomiting and nausea, tingling or weakness in the hands and feet, organ damage, memory loss, behavioral changes and breathing problems. Anemia may also occur, and children with this problem often develop weak bones. 

It's important for patients to interpret heavy metal tests carefully; many tests show a small level of metals in the bloodstream, but these metals may not be harmful at these percentages. When multiple tests over time show heavy metal exposure or when other symptoms are present, treatment becomes more important. People who show higher than safe levels on a heavy metals profile may wish to consider chelation therapy, which can bind these metals and keep them from becoming dangerous.
