Test Details
Methodology
Inductively-coupled plasma/mass spectrometry (ICP/MS)
Result Turnaround Time
2 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Test Includes
Cadmium, urine; creatinine, urine; cadmium:creatinine ratio; cadmium, urine (24-hour)
Use
Monitor exposure to cadmium
Special Instructions
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.
Limitations
This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration.
Specimen Requirements
Specimen
Urine (random or 24-hour)
Volume
5 mL
Minimum Volume
2.5 mL
Container
Plastic urine container, no preservative
Collection Instructions
Sampling time is not critical for industrial exposure monitoring. Metals with timing “not critical” have very long elimination half-lives and accumulate in the body over years, some for a lifetime. After a couple of weeks of exposure, specimens can be collected at any time.
Stability Requirements
Temperature | Period |
|---|---|
Room temperature | 14 days |
Refrigerated | 14 days |
Frozen | 14 days |
Freeze/thaw cycles | Stable x3 |
Reference Range
• Environmental exposure: <2.0 μg/g creatinine, <3.0 μg/24 hours
• Occupational exposure: OSHA Cadmium Standard: 3.0 μg/g creatinine, BEI®: 5.0 μg/g creatinine1
Storage Instructions
Maintain specimen at room temperature.
