Patient's question:
5-year-old picky eater, poor concentration, fidgeting during tutoring, unclear about the previous treatment and its effectiveness: No treatment. What kind of help is expected: Hope to get clarification.Doctor's answer:
Currently, the diagnosis and stratification of childhood lead poisoning are primarily based on blood lead levels:I. Blood lead < 100 μg/L (<0.483 μmol/L), relatively safe (embryonic and developmental toxicity have been observed, with an increased risk of miscarriage in pregnant women);
II. Blood lead 100–199 μg/L (0.483–0.917 μmol/L), interference with heme catabolism, increased nerve conduction velocity;
