What is Mercury Blood test?
Mercury is a toxic heavy metal that is present in various forms in the environment. It is also used in everyday products and produced by the combustion of fossil fuel.
Depending on its source and composition, mercury has three different forms:
- Metallic mercury (present in dental fillings, batteries and thermometers)
- Inorganic mercury (found in cosmetics such as skin lightening creams)
- Organic mercury (such as methyl mercury, mostly found in seafood)
Mercury blood test is mainly performed to look for excessive amount of methyl mercury and other organic mercury compounds in the body.
Small amount of mercury is not harmful to health. However, acute exposure to high levels of mercury or long term and consistent exposure to small quantities of this heavy metal may lead to toxicity. Individuals who work in factories/industries which use this heavy metal are at a higher risk and tend to develop symptoms of mercury exposure over time.
Additionally, smoke from factories, hospital incinerators and power plants can cause mercury exposure through inhalation.
