Dr. Crist offers toxic metal testing and treatment for his patients. He tests for toxic metals, such as lead, mercury, cadmium, tin and other toxic elements. About 90% of patients that Dr. Crist tested had elevated levels. Toxic metal elevations can cause some of the same symptoms as those caused by a tick-borne illness, and patients with a tick-borne illness often feel better when their toxic metal elevations are treated. Those without a tick-borne illness also feel better with treatment for toxic metals. After testing, Dr. Crist will review treatment options for detoxing toxic metals out of your body.
