Lead Poisoning Diagnosis and Treatment
Symptoms and Effects
- The American Academy of Pediatrics recommends prompt identification of symptoms and blood lead level-based treatment, with chelation therapy indicated for levels above 45 μg/dL in children and 70 μg/dL in adults with symptoms 1
- Developmental delays and decreased intelligence in children are associated with lead poisoning 1
- Cognitive dysfunction in adults is a potential effect of lead exposure 2
- Hypertension, renal dysfunction, and reproductive problems are possible outcomes of lead poisoning in adults 2
- Irritability and behavioral changes are common neurological symptoms of lead poisoning in children 3
Diagnosis and Testing
- Blood lead level (BLL) is the primary diagnostic test for lead poisoning 3
- Abdominal radiography should be considered for children with pica behavior to diagnose lead poisoning 1
Treatment Protocol
- For children with BLL <5 μg/dL, review results with family, provide anticipatory guidance, assess nutrition and development, and repeat testing in 6-12 months if high risk 3
- For children with BLL 5-14 μg/dL, notify local health authorities, identify and eliminate lead sources, retest within 1-3 months, provide nutritional counseling, screen for iron deficiency, and monitor development closely 1
- For adults with BLL ≥80 μg/dL, urgent medical evaluation is necessary, and chelation is indicated if symptomatic and/or BLL ≥100 μg/dL 4
- Pregnant women should avoid lead exposure that would result in BLL >5 μg/dL 2
