CPT 82300; 82570
Synonyms
  • Cd, Urine

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.

Footnotes

1. BEI® (Biological Exposure Indices) based on 2010 Recommendations of the American Conference of Governmental Industrial Hygienists (ACGIH).

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.
