26284 Cadmium Occupational Exposure, Random, Urine (CDUOE)

Cadmium Occupational Exposure, Random, Urine (CDUOE)
Test Code: CDUOESO
Synonyms/Keywords

​Cadmium (Cd), Cd (Cadmium)

Useful For

​Detecting occupational exposure to cadmium, a toxic heavy metal in random urine specimens. 

Specimen Requirements
Specimen TypePreferred Container/TubeAcceptable Container/TubeSpecimen VolumeSpecimen Minimum Volume
(allows for 1 repeat)
Pediatric Minimum Volume
(no repeat)
Random ​Urine​Clean, plastic urine container with no metal cap or glued insert​3 mL​1.5 mL
Collection Processing Instructions

​High concentrations of gadolinium and iodine are known to interfere with most metals tests. If either gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.

Specimen Stability Information
Specimen TypeTemperatureTime
​Urine ​ ​​Refrigerated (preferred)​28 days
​Frozen​28 days
​Ambient​14 days
Rejection Criteria
All specimens will be evaluated at Mayo Clinic Laboratories for test suitability. 
Interference

​Collection of urine specimens through a catheter frequently results in elevated values, because rubber contains trace amounts of cadmium that are extracted as urine passes through the catheter.

Performing Laboratory Information
Performing LocationDay(s) Test PerformedReport AvailableMethodology/Instrumentation
​Mayo Clinic Laboratories​Monday through Saturday​1 to 4 days

CDOU: ​Inductively Coupled Plasma-Mass Spectrometry (ICP-MS)

CRETR:  Enzymatic Colorimetric Assay

Reference Range Information
Performing LocationReference Range
​Mayo Clinic Laboratories​Biological Exposure Indices (BEI): <5.0 mcg/g creatinine
Interpretation

Urine cadmium levels primarily reflect total body burden of cadmium. Cadmium excretion above 3.0 mcg/g creatinine indicates significant exposure to cadmium.

For occupational testing, the Occupational Safety and Health Administration (OSHA) cadmium standard is below 3.0 mcg/g creatine and the biological exposure index is 5 mcg/g creatinine.
