- Elevated levels of blood lead should be confirmed with a second specimen before remedial action is instituted.
- Elevated capillary blood specimens should be repeated using a venous specimen due to possible contamination.
|Less than 10 ug/dL
||Not action required.
||Identify and minimize exposure.
||Remove from exposure if symptomatic.
||Remove from lead exposure. Immediate medical evaluation required.
|Greater than or equal to 80.0 ug/dL
||Chelation may be indicated if symptomatic. Seek a consultation.
Atomic Absorption Spectrophotometry.
Elevated results may be due to skin or collection-related contamination, including use of a noncertified lead-free tube. Elevated levels of blood lead should be confirmed with a second specimen collected in a lead-free tube.
This assay aids in the evaluation of lead toxicity and poisoning.
