Target exams
Red flags
- Child with seizures, altered consciousness or encephalopathy and possible lead exposure — emergency care and specialist chelation pathway
- Venous blood lead at or above 45 micrograms/dL — urgent specialist/toxicology input and source removal
- Elevated capillary lead without venous confirmation — confirm before chelation decisions
- Child returning to an unremediated lead-hazard home after treatment — re-exposure is expected
- Pica with possible paint chips or radiopaque material on abdominal imaging — decontamination and source control
- Sibling or household contact of a confirmed case not yet assessed

Overview & Definition
Lead has no biological role in the child. Measurable blood lead, even at levels once called “acceptable,” links to lower IQ, attention problems and poorer school performance. Population blood lead fell after controls on petrol and paint, but residual hazards remain in housing, water, soil, consumer products and some traditional remedies or cosmetics. Your job is primary prevention first, then early detection and source control. [2] [5]
Lead exposure means contact that raises body burden. Lead poisoning (toxicity) usually refers to higher levels with illness that needs urgent medical care. Most modern paediatric cases are silent. The laboratory value alone never tells the whole story — the home, habits and developmental trajectory matter. [1]
