Interpretive Data: 

CDC Blood Lead Reference Value: 3.5 µg/dL

  • CDC classification in children (<=15 years of age):= 10µg/dL or as indicated by local health dept. 20-44µg/dL: Same as above. Complete history and physical exam, assess for signs and symptoms. 45µg/dL or higher: Same as above. Medical intervention including physical and neurological exam. Consider chelation therapy. Contact state or local health dept. 
  • CDC Classification in Adults (>=16 years of age):
    • <3.5 ug/dL: No action needed. Monitor BLL if ongoing exposure
    • 3.5-9 ug/dL: Discuss health risks. Minimize exposure. Reduce lead exposure for women who are or may become pregnant
    • 10-19 ug/dL: Decrease exposure. Consider removal from lead exposure for certain medical conditions or BLL >10 for extended period. Increase monitoring and repeat BLL in 3 months.
    • 20-29 ug/dL: Remove from Lead exposure. Prompt medical evaluation.
    • 50-79 ug/dL: Remove from lead exposure. Prompt medical evaluation. Consider Chelation therapy with significant symptoms or signs of lead toxicity.
    • >80 ug/g/dL: remove from lead exposure. Urgent medical evaluation. Probably Chelation therapy.
