Mercury is often abbreviated Hg. It may be breathed in, ingested or absorbed through the skin and is toxic. As a vapor, mercury is odorless.
Urinary mercury testing is considered a very accurate way to assess whether or not you have been exposed to the inorganic form of the heavy metal. There is also an organic form of mercury, which can become toxic in the body but this form of mercury is best detected in a blood test sample.
A urine mercury test measures mercury excretion from the body over 24 hours, both before and after a “provocation” or “detox” compound is ingested. A provocation compound increases the excretion of a substance such as toxic metals. EDTA, DMSA, and DMPS are examples of provocation compounds.
Taking the urine mercury test without a provocation compound reveals mercury in the urine whether or not there are high levels of mercury in the body. When the provocation compound is ingested, mercury levels increase in the urine. Urinary mercury has been found to be an accurate determination of the amount of the heavy metal in the body.
