This test measures total mercury in your blood to evaluate recent or ongoing exposure. Elevated mercury can cause neurological symptoms, kidney damage, and immune dysfunction. Common sources include high-mercury fish (tuna, swordfish), dental amalgam fillings, and industrial exposure. Blood mercury reflects recent exposure (weeks), while hair or urine tests reflect chronic exposure.
Environmental and toxin testing measures exposure to heavy metals, industrial chemicals, and other environmental hazards that can drive chronic symptoms and long-term health risk.
Individuals with known or suspected occupational exposure, residents of older homes (lead, mold), people eating large quantities of certain fish (mercury), and anyone with unexplained chronic symptoms.
