Blood lead levels in the range of 5-9 mcg/dL have been associated with adverse health effects in children aged 6 years and younger. Patient management varies by age and CDC Blood Level Range. Refer to the CDC website regarding Lead Publications/Case Management for recommended interventions.

Clinical Information: Blood lead is useful in detecting industrial, dietary, and accidental exposure to lead and to monitor detoxification therapy. Children are especially susceptible to neurologic damage from lead and acute neurology toxicity may develop without previous symptoms.
