This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration.
Inductively-coupled plasma/mass spectrometry (ICP/MS)
• Environmental exposure: 0.0−9.9 μg/g creatinine; 0.0−7.0 μg/24 hours
• Occupational exposure (soluble compounds): 30 μg/g creatinine1
Urine (random or 24-hour)
Plastic urine container, no preservative
Optional protocol: Instruct the patient to void at 8 AM and discard the specimen. Then collect all urine including the final specimen voided at the end of the 24-hour collection period (ie, 8 AM the next morning). Avoid contact with metal during collection. Screw the lid on securely.
Maintain specimen at room temperature.
State 24-hour volume on the request form, if applicable. Do not use preservative. Preservatives used for routine analysis may contain mercuric oxide (ie, Stabilur), which interferes with all metal testing. If both urinalysis and metal testing are ordered, please submit a separate urine specimen (containing no additive) for the metal testing.
