Cadmium, 24‑Hour Urine
Use
This test evaluates exposure to the toxic metal cadmium by measuring its concentration in a 24‑hour urine sample, aiding in the detection and monitoring of cadmium exposure which can be harmful to renal, pulmonary, gastrointestinal, neurologic, reproductive, and cardiovascular systems. It is intended for individuals with potential cadmium exposure due to environmental or occupational sources, or those exhibiting symptoms consistent with cadmium toxicity.
Special Instructions
Avoid seafood consumption for 48 hours prior to collection. Use an acid‑washed or trace‑metal free container for collection; avoid work‑site collection. Collect a well‑mixed 24‑hour urine; submission in non‑trace element containers may be accepted but may prompt recommendation for re‑submission.
Limitations
Elevated results from specimens collected in non‑trace element tubes or non‑metal‑free containers may not accurately reflect true cadmium burden, and may trigger a note recommending re‑collection. Specimen collection at the work site may contaminate results.
