Maine CDC Health Advisory

November 9, 2022

Change to Guidelines for Specimen Collection Tubes for Venous Whole Blood Lead Analyses

The purpose of this advisory is to inform clinical laboratories and health care providers in Maine about changes to guidelines for submitting venous whole blood lead specimens to the Maine CDC's Health and Environmental Testing Laboratory (HETL). HETL is updating its guidelines given concerns, recently identified in Maine and nationally, that some lavender-top specimen collection tubes may be contaminated with lead, potentially producing falsely elevated results.
