Cook County Public Health Reminds Families to Get Their Children Tested for Lead
The new state lead testing requirements, which took effect July 1, 2026, require all children to receive blood lead tests at ages 12 months and 24 months, regardless of where they live. Also, children 6 years old and younger must receive a lead exposure risk assessment through a questionnaire administered by a healthcare provider. Previously, Illinois lead testing requirements applied only to children living in high-risk ZIP codes.
