Synonyms
- Cd, Urine
Test Includes
Cadmium, urine; creatinine, urine; cadmium:creatinine ratio; cadmium, urine (24-hour)
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.
Expected 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.

Specimen Requirements
Specimen
Urine (random or 24-hour)
Volume
5 mL
Minimum Volume
2.5 mL
Container
Plastic urine container, no preservative
Collection
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.
Storage Instructions
Maintain specimen at room temperature.
Stability Requirements
Temperature | Period |
|---|---|
Room temperature | 14 days |
Refrigerated | 14 days |
Frozen | 14 days |
Freeze/thaw cycles | Stable x3 |
Test Details
Use
Monitor exposure to cadmium
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.
Methodology
Inductively-coupled plasma/mass spectrometry (ICP/MS)
Reference Interval
• 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
Footnotes
