Dr. Amy Nett: Most often, I do Quicksilver. You can do the mercury tri-test, and you need to species it out, organic and inorganic mercury, and you can do their blood metals panel. If you need to get lead, cadmium, arsenic, Doctor’s Data also has toxic elements profile. I tend not to do provoke testing because you never know if somebody is going to have a strong reaction to the provoking agent. I tend to just do do blood testing without provocation.
