Biomarker Reference · Hg
Mercury (Urine) (Hg) is a clinical biomarker used in heavy-metals-toxicology assessment. Mercury exists in elemental, inorganic, and organic (methylmercury) forms. It is measured in 2 laboratory tests on BiomarkersLabs.com.
Mercury exists in elemental, inorganic, and organic (methylmercury) forms. Urinary mercury primarily reflects inorganic mercury and elemental mercury vapour exposure; methylmercury from fish is predominantly excreted in faeces, so urine mercury is less sensitive for dietary methylmercury but useful for dental amalgam vapour and occupational exposure. Renal excretion is the main route for inorganic mercury, with a biological half-life of weeks to months.
Urinary mercury is the biomarker of choice for chronic elemental or inorganic mercury exposure. Elevations may arise from dental amalgam, occupational exposure (mining, manufacturing, dentistry), or contaminated water. Symptoms of chronic toxicity include tremor, cognitive impairment, and renal tubular dysfunction. Provocation testing with chelators is not recommended for diagnosis outside controlled research.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
