Reference interval

Clinical significance

  • 50% of children in the U.S. still have detectable levels of lead in blood[8]
    • in Nebraska, Missouri, Michigan, & Iowa, >75% of children have detectable levels of lead in blood
  • higher lead in blood correlate with poverty, race, & housing

Increases

Notes

  • falsely low blood lead levels reported with Magellan Diagnostics' LeadCare<TM>Analyzers (May 2017)[7]
    • the tube stoppers contain thiuram that can sometimes release sulfur-containing gases, which may dissolve into the blood sample & bind the lead particles[7]
