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.
