Heavy Metals Scrn with DemographicsSpecimen Type
Whole bloodNecessary Information
If not ordering electronically, the Lead and Heavy Metals Reporting (T491) is required. Send with specimen.
Specimen Required
Patient Preparation: High concentrations of gadolinium and iodine are known to potentially interfere with most inductively coupled plasma mass spectrometry-based metal tests. If either gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.
Supplies: Metal Free B-D Tube (EDTA), 6 mL (T183)
Container/Tube: Royal blue top (EDTA) plastic trace element blood collection tube
Specimen Volume: Full tube
Collection Instructions:
1. See Metals Analysis Specimen Collection and Transport for complete instructions.
2. Send whole blood specimen in original collection tube. Do not aliquot.
