HelpTest ID HMUOE Heavy Metal Occupational Exposure, with Reflex, Random, Urine
Specimen Required
Patient Preparation:
1. Patient should not eat seafood for a 48-hour period prior to start of collection.
2. High concentrations of gadolinium and iodine are known to interfere with most metal tests. If either gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.
