Colorado’s lead screening guidelines 
Colorado does not recommend universal testing for all young children. Instead Colorado recommends targeted testing for lead levels in blood based on responses to a risk-based questionairre. If the the questionairre indicates a high risk for lead poisoning, children should be tested at 12 months and 24 months of age, using either a capillary or venous blood specimen.  
Colorado has adopted CDC's guidance on case management for lead. At levels 20 µg/dL or higher, call the Rocky Mountain Poison & Drug Center for consultation services / medical treatment at 303-739-1123 or 800-332-3073. 
Board of Health lead reporting requirements
Blood Lead Levels (BLLs) have been a reportable condition in Colorado since 1997. Under the state’s reporting law, all laboratories performing blood lead tests are required to report the results of those tests directly to the Colorado Department of Public Health and Environment.
  • ​If age >18, report blood lead levels ≥5μg/dL within thirty (30) days of result.
  • If age ≤18, report all blood lead levels as follows:
    • blood lead levels <5μg/dL within thirty (30) days of result.
    • blood lead levels ≥5μg/dL within seven (7) days of result.
  • Must include the following information:
    • The disease or condition being reported;
    • Patient's name, date of birth, sex, address (including city, county, and phone number);
    • Physician's name, address and telephone number;
    • Specimen type, collection date, result date, numerical result in μg/dL.
