Lead, Whole Blood (Adult)
Use
Monitor exposure to lead
Special Instructions
The test does not require specific sampling time for industrial exposure monitoring. Lead has a long elimination half-life, allowing specimens to be collected at any time after a couple of weeks of exposure. Blood is the preferred specimen type to measure acute or recent exposure to lead. Clotted specimens will be rejected. Ensure proper collection using specified containers for accurate results.
Limitations
This test was developed and its performance characteristics determined by Labcorp and has not been cleared or approved by the FDA. Potential hematologic consequences of lead toxicity include basophilic stippling, mild anemia, and reticulocytosis. Other toxic effects can manifest in various organ systems, and some may appear later in life, indicating accumulative exposure. Acute lead exposure is rare, toxicity generally occurs from prolonged or high-level contact with lead-containing materials.
