Laboratory

Sent to Warde Medical Laboratory, Ann Arbor, MI.

Performed

Sunday – Friday.
Results available in 2-3 days. 

Reference Range

By report.

Test Methodology

Atomic Absorption Spectrophotometry.

Interpretation

Elevated results may be due to skin or collection-related contamination, including use of a non-certified lead-free tube. Elevated levels of blood lead should be confirmed with a second specimen collected in a lead-free tube.

Clinical Utility

This assay aids in the evaluation of lead toxicity and poisoning.
