Mercury Blood Test in Colorado

What this test measures

Mercury enters the body through food, air, or skin contact, and the form of mercury influences how it behaves. Methylmercury, found in some fish, is absorbed efficiently and can accumulate over time. Inorganic and elemental mercury are more often linked to occupational settings, certain dental materials, or specific products. Blood levels generally reflect exposure over the recent period rather than a lifetime.

Whole blood is commonly used for mercury testing, and some laboratories can measure different forms separately. Urine testing is often used to assess inorganic mercury exposure, while blood is preferred for methylmercury. Iron status and other metals such as lead or arsenic may be measured at the same time when a broader exposure evaluation is needed.

People may order this test after a known or suspected exposure, when a workplace program requires monitoring, or when symptoms raise concern about metal exposure. A qualified healthcare provider interprets the result with the exposure history, dietary habits, and other test findings. The test is not a stand-alone diagnosis.
