Question
What level of lead in a two-year-old’s blood is considered high?
Answer
Generally, when the lead level reaches or exceeds 1.44 to 2.4 μmol/L, it has diagnostic significance. Typically, if a child’s blood lead level exceeds 2.88 μmol/L, it may cause noticeable symptoms and signs of neurological damage. If the lead level remains consistently above 1.92 μmol/L (40 μg/dl), it may result in varying degrees of neurological damage.
