Also known as: Cd, Urine

Clinical Use

Order Test

Use

Monitor exposure to cadmium

Special Instructions

Not provided.

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.
