22391 Cadmium, Urine, 24 hour (CDU)

Cadmium, Urine, 24 hour (CDU)
Test Code: CADUSO
Synonyms/Keywords
Cadmium (Cd), Cd (Cadmium)
Useful For
Detecting exposure to cadmium, a toxic heavy metal
Specimen Requirements
Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)
Pediatric Minimum Volume
(no repeat)
Urine​ Plastic, 10-mL urine tube or clean plastic aliquot container with no metal cap or glued insert​ 10 mL​ 2 mL​
Collection Processing Instructions
Collection Instructions:
1. Collect urine for 24 hours.
2. Refrigerate specimen within 4 hours of completion of 24-hour collection
Additional Information:
1. 24-hour volume is required.
2. 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 Type Temperature Time
​Urine ​ ​ Refrigerated (preferred)​ ​28 days
​Ambient ​28 days
​Frozen ​28 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.

0-17 years: not established
> or =18 years: <0.7 mcg/24 hour
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 less than 3.0 mcg/g creatine and the biological exposure index is 5 mcg/g creatinine.
