How to Use This Course
This page refers to a blood lead level of 5 micrograms per deciliter (μg/dL) as the CDC’s blood lead reference value. As of October 28, 2021, CDC uses a blood lead reference value of 3.5 micrograms per deciliter to identify children with blood lead levels that are higher than most children’s levels. This new level is based on the U.S. population of children ages 1–5 years who represent the top 2.5% of children with the highest blood lead levels. For more information, refer to Blood Lead Reference Value.
