Objective To investigate the relationship between common symptoms and blood lead in pediatric outpatients. Methods Blood lead levels were measured by atomic absorption spectrophotometry in 487 children with symptoms and 80 control children. Results The average level of blood lead in children of all age groups was higher than that of the control group (P <0.01), and the incidence of lead poisoning was higher than that of the control group (P <0 05). Conclusion Lead poisoning may be the cause of some unexplained children’s symptoms, blood lead should be promptly detected to help diagnose
