Clinical Significance
Hematologic consequences ascribed to lead toxicity may be basophilic stippling, mild anemia, and reticulocytosis. Other characteristics of toxicity may include increased urine δ-aminolevulinic acid, increased erythrocyte protoporphyrins, and decreased aminolevulinic acid dehydrase. Lead lines on gums or at the metaphyses of long bones in children may also be present.2 Early symptoms of lead poisoning include anorexia, apathy or irritability, fatigue, and anemia.3 Toxic effects include GI distress, joint pain, colic, headache, stupor, convulsions, and coma.
