Lead, Venous, with Demographics, Blood
Use
Detecting lead toxicity in venous blood specimens. Lead is a heavy metal that acts as a toxin to humans and is frequently found in the environment. Testing for levels of lead in the blood is crucial, as it can enter the human body through various means such as water, food, and air. The detection aims to aid in diagnosing lead exposure and toxicity which can affect multiple organ systems and result in conditions requiring medical intervention, including chelation therapy.
Special Instructions
If testing is needed on a capillary specimen, order PBDC / Lead, Capillary, with Demographics, Blood. Ensure specimen container is not opened or used for any other testing before shipping. Use specified supplies and follow specific container requirements.
Limitations
High concentrations of gadolinium and iodine may interfere with inductively coupled plasma mass spectrometry-based metal tests. Specimens collected within 96 hours of receiving gadolinium- or iodine-containing contrast media may yield inaccurate results. Ensure strict adherence to specimen volume and handling instructions to avoid degradation or contamination affecting test outcomes.
