A mercury blood test measures the amount of mercury in your bloodstream. It is usually ordered when someone has known or suspected exposure to mercury, or when symptoms suggest possible mercury toxicity.

What it measures

  • Total mercury — The overall amount of mercury in the blood sample.
  • Inorganic mercury — Mercury from industrial or chemical sources, such as certain workplace exposures.
  • Organic mercury — Mercury bound to carbon, commonly from eating certain fish.
  • Methylmercury — A specific organic form often linked to fish consumption.

Who it is for

Doctors may order this test for people with workplace exposure, symptoms such as numbness or tremors, or a known spill or release. It may also be used to monitor someone already being followed for mercury exposure.

Preparation

No fasting is usually required. Tell your clinician about recent fish meals, dental work, or any possible mercury exposure, since timing can affect the result.

Results and what they mean

Results are reported as a number, often in micrograms per liter, and are compared with a reference range. Your clinician interprets the result along with your history, symptoms, and other tests. This is general information, not medical advice; discuss your results with a qualified clinician.
