Cadmium, Random Urine
Use
Measurement of urinary cadmium levels (often creatinine‑corrected) provides an indicator of body burden/exposure to cadmium, a toxic heavy metal that primarily affects renal tubular function. Expressing results relative to urinary creatinine helps normalize for urine concentration variability and improve interpretability in occupational and environmental exposures.

Limitations
Urine cadmium collection via non‑metal‑free containers may result in contamination and false‑elevated values; catheter‑collected specimens may leach cadmium from rubber components and lead to spurious elevated results; proper specimen handling (trace‑metal‑free containers) is essential ([mayocliniclabs.com](https://www.mayocliniclabs.com/test-catalog/overview/608896?utm_source=openai)).
