Overview

An elevated concentration of venous blood lead levels is diagnostic of lead poisoning.

Laboratory Findings

• Laboratory findings consistent with the diagnosis of lead poisoning include:
  • Basophilic stippling of red blood cells
  • Iron deficiency anemia (microcytosis and hypochromia)
  • Elevated venous blood lead levels
  • K-fluorescent X-ray metering can measure bone-lead.

Shown below is an image depicting basophilic stippling in a blood smear of a patient with lead poisoning.
