Cadmium, 24 Hour, Urine
Use
Detects exposure to cadmium, a toxic heavy metal, in 24‑hour urine specimens. Cadmium accumulates in the kidneys and urine levels reflect total body burden, and elevated excretion (>3.0 µg/g creatinine) indicates significant exposure, particularly in occupational settings where OSHA standard is <3.0 µg/g creatinine and BEI is 5.0 µg/g creatinine.
Special Instructions
Not provided.
Limitations
Results may be elevated if urine is collected via catheter. High concentrations of gadolinium or iodine (e.g., from contrast media) may interfere with ICP‑MS/MS and specimens should not be collected within 96 hours of administration.
