Lead, Capillary, with Demographics, Blood
Use
Detecting lead toxicity with capillary collections. Lead is a heavy metal naturally found in the environment that can be an acute and chronic toxin. Exposure to lead can occur through ingestion, inhalation, or dermal contact. It is released into the environment from sources such as mining, manufacturing, and burning of fossil fuels. Lead can cause neurological damage and anemia, particularly in children, due to its effect on hemoglobin synthesis and its accumulation in soft tissues and bones.
Special Instructions
Not provided.
Limitations
High concentrations of gadolinium and iodine can interfere with mass spectrometry-based metal testing. Specimen collection should be delayed for 96 hours if these substances have been administered. Capillary blood collection may be contaminated, requiring confirmation by venous testing. This test does not differentiate lead exposure from other possible causes of elevated lead levels, such as environmental contamination.
