| 0-10 µg/L
This test measures total mercury, whereas the reference interval relates to inorganic mercury concentrations. Dietary and non-occupational exposure to organic mercury species may contribute to an elevated total mercury result. NOTE: Elevated results from noncertified trace element-free collection tubes may be due to contamination. Elevated concentrations of trace elements in blood should be confirmed with a second specimen collected in a tube designed for trace element determinations, such as a royal blue (Na2EDTA) tube. |
