Overview

Lead poisoning must be differentiated from megaloblastic anemia[1], carpal tunnel syndrome[2], Guillain–Barré syndrome, renal colic, appendicitis, encephalitis in adults, and viral gastroenteritis in children.[3], constipation, abdominal colic[4], iron deficiency, subdural hematoma, neoplasms of the central nervous system, emotional and behavior disorders, and intellectual disability.[5] [6]
