MDHHS Updates Blood Lead Reference Value Data
Update: Oct 17-28, 2022
On October 20, the Michigan Department of Health and Human Services (MDHHS) announced a change in blood lead data available for Michigan children. In May 2022, the Centers for Disease Control and Prevention (CDC) updated their blood lead reference value (BLRV) from 5 ug/dL to 3.5 ug/dL. In response, MDHHS changed its definition to match the CDC.
In 2021, more than 3,400 Michigan children had an elevated blood level of 3.5 ug/dL or higher. More than half of those children had a blood level of 5 ug/dL or higher. Detection at a lower reference level will help identify more children who need public health services and further medical evaluation. It is also helpful for identifying communities that need prioritized interventions to reduce lead exposure.
Elevated blood lead level tracking is available online through Michigan Environmental Public Health Tracking (MiTracking) for those with a blood lead of 3.5 ug/dL or higher. Data is available at the state, county, and local health department, and zip code levels.
