Reportable Venous Lead Levels

On January 1, 2025 reportable venous lead levels in children ages 0 to 6 years reduced from 5µg/dL to 3.5µg/dL. An elevated lead level is a mandatory reportable lab.

Lead Case Management Services

The Health Department provides case management services to all children (through the age of 15 years) and pregnant persons who are residents with a DeKalb County address with an elevated lead level.

Lead Testing Services

The Health Department offers capillary lead testing. Please contact us at 8115-748-2467 if you need an alternative site for the testing.

Lead Testing Guidelines

Please be sure to complete the IL Childhood Lead Risk Questionnaire for all children 6 years of age or younger. All children must be assessed for risk of lead exposure and tested, if necessary, for enrollment into daycare, preschool and kindergarten. Complete the IL Childhood Lead Risk Questionnaire during a well-child or health care visit for children between 12 and 24 months of age (at a minimum) and once a year at annual well-child visits at ages 3,4,5 and 6 years.

All blood lead test results must be submitted to the Illinois Lead Program.
