Why This Biomarker Matters
Mercury is toxic and can accumulate in organs, causing neurological damage, kidney problems, and developmental harm. Monitoring exposure is important for occupational or environmental safety.

Overview
Mercury is a toxic heavy metal that can accumulate in the body through contaminated fish, occupational exposure, or environmental sources. A mercury test measures exposure levels in urine or blood. Elevated mercury can cause neurological symptoms, kidney damage, and developmental problems in children. Testing is typically ordered for occupational monitoring or suspected toxic exposure.
