Does Vibrant’s Heavy Metals test measure methylmercury or ethylmercury?

Vibrant's Heavy Metals test is measured using Triple Quadrupole Inductively Coupled Plasma-Mass Spectrometry (ICP-MS/MS) and analyzes the total amount of mercury (elemental, inorganic and organic) present in urine. We do not individually measure specific forms of mercury such as methylmercury or ethylmercury. Elevated mercury in urine usually indicates exposure to an elemental or inorganic source of mercury. Additionally, based on possible demethylation of methylmercury within the body, urine may also represent a mixture of dietary methylmercury and inorganic mercury. Seafood consumption can contribute to urinary mercury levels (up to 30%), which is consistent with the suggestion that due to demethylation processes in the human body, a certain proportion of urinary mercury can originate from dietary consumption of fish/seafood.
