Understanding Lab Tests for Mercury Poisoning
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Mercury poisoning occurs when mercury accumulates in the body to toxic levels, potentially causing serious neurological and physical symptoms. This condition requires specific laboratory testing to accurately diagnose, as symptoms can overlap with other neurological disorders.
Recommended Test
Heavy Metals Panel, Blood
This comprehensive blood test directly measures mercury levels along with other heavy metals in the bloodstream. Elevated mercury concentrations can confirm mercury poisoning and help explain symptoms such as muscle weakness, lack of coordination, numbness in the hands and feet, and potential damage to hearing and speech functions.

Diagnosing Mercury Poisoning
Mercury exposure can occur through contaminated fish consumption, dental amalgams, industrial exposure, or broken thermometers. Because mercury poisoning symptoms like muscle weakness, coordination problems, and numbness can mimic other conditions, blood testing is essential for confirming elevated mercury levels and establishing a definitive diagnosis.
Understanding Mercury Toxicity
Mercury is a toxic heavy metal that can accumulate in body tissues over time. When blood mercury levels exceed safe thresholds, it can interfere with nervous system function, leading to the characteristic symptoms of mercury poisoning. Early detection through blood testing is crucial for preventing permanent neurological damage.
