About this panel

This panel reports levels of seven separate heavy metals in a 7 mL urine sample, measured by Inductively Coupled Plasma/Mass Spectrometry: arsenic, cadmium, cobalt, lead, mercury and thallium, along with creatinine, which is used to account for how concentrated or dilute the urine sample is.

Quest lists this panel as a way to assess exposure to potentially harmful toxic substances, and it asks people to avoid seafood before collection, since certain seafood can affect some of the metals the panel measures.
