Mercury, Blood

Blood Mercury measures exposure to mercury, a toxic heavy metal, primarily reflecting recent intake of methylmercury (from contaminated fish/seafood). Elemental/inorganic mercury exposure (e.g., dental amalgams, industrial) is better assessed via urine. Mercury is a neurotoxin, affecting the brain, nervous system, and kidneys. Minimizing exposure and levels is crucial. Levels <5 ug/L are typical background; >10 ug/L suggests significant exposure.
