Ordering Guidance
The Centers for Disease Control and Prevention recommends venous collection of samples for lead testing. Capillary lead testing is acceptable for pediatrics and patients with phlebotomy considerations, but capillary blood collection may be more susceptible to contamination. Elevated capillary blood levels must be confirmed with a venous lead blood test. See PBDV / Lead, Venous, with Demographics, Blood.
Specimen Required
Patient Preparation: High concentrations of gadolinium and iodine are known to potentially interfere with most inductively coupled plasma mass spectrometry-based metal testing. If either gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.
Supplies: Microtainer (EDTA) Tube, 0.5 mL (T174)
Collection Container/Tube: BD Microtainer with EDTA
Specimen Volume: 0.4 mL
Collection Instructions:
1. See Metals Analysis Specimen Collection and Transport for complete instructions.
2. Send whole blood specimen in original tube. Do not aliquot.
Forms
