## Overview[edit | edit source]

Elevated venous blood lead levels and basophilic stippling of red blood cells on peripheral smear are the the most important and diagnostic laboratory findings in lead poisoning.

## Laboratory Findings[edit | edit source]

* Laboratory findings consistent with the diagnosis of lead poisoning include:
* Basophilic stippling of red blood cells [1]
* Iron deficiency anemia (microcytosis and hypochromia) [2]
* 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.
