Heavy metals testing is used to screen for or to diagnose heavy metal poisoning in those who may have been acutely or chronically exposed to one or more heavy metals and to monitor excessive metal concentrations in those who work with various heavy metals. Such occupations include construction work, mining, radiator repair shops, and firing ranges. Testing is also conducted to monitor the effectiveness of chelation therapy, a treatment to rid the body of high amounts of a heavy metal. Heavy metal panels are set up in groups of tests that mirror potential metal exposures. A laboratory may offer several different groupings that are specific for either blood or urine. A healthcare practitioner will order the metals panel that corresponds to the person’s occupation, hobby, suspected exposure, and/or clinical symptoms.
