HelpTest ID NIUC Nickel/Creatinine Ratio, Random, Urine
Specimen Required
Only orderable as part of a profile. For more information see NIUCR / Nickel/Creatinine Ratio, Random, Urine.
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: Urine Tubes, 10 mL (T068)
Container/Tube: Plastic, 10-mL urine tube or clean, plastic aliquot container with no metal cap or glued insert
Specimen Volume: 2.55 mL
Collection Instructions:
1. Collect a random urine specimen
2. See Metals Analysis Specimen Collection and Transport for complete instructions.
