Cadmium, Urine
Also known as: Cd, Urine
Use
Monitor exposure to cadmium
Special Instructions
Ensure not to use a preservative as it may interfere with the test results, particularly those containing mercuric oxide. If urinalysis and metal testing are both ordered, they require separate urine specimens to prevent inaccuracies.
Limitations
The test is not cleared or approved by the FDA; results should be interpreted with this context. It is important to note that cadmium has a long biological half-life, leading to its accumulation over time. This means urinary cadmium levels reflect chronic exposure rather than acute changes, limiting its utility in assessing recent exposure to cadmium.

Collection Instructions
Sampling time is not critical for industrial exposure monitoring. The urine sample should be collected without preservatives to prevent interference. After exposure, specimens can be collected at any time due to cadmium's long elimination half-lives.
Storage Instructions
Maintain specimen at room temperature.
