Cadmium/Creatinine Ratio, Urine
Use
Detecting exposure to cadmium using random urine specimens. Cadmium excretion above 3.0 µg/g creatinine indicates significant exposure to cadmium; results above 15 µg/g creatinine are considered indicative of severe exposure. The ratio reflects total body burden and is useful for occupational monitoring where the OSHA standard is less than 3.0 µg/g creatinine and the biological exposure index is 5 µg/g creatinine.
Special Instructions
Only orderable as part of profile (e.g., CDUCR or HMUCR). Method used is Triple‑Quadrupole Inductively Coupled Plasma Mass Spectrometry (ICP‑MS/MS).
Limitations
Collection of urine specimens through a catheter frequently results in elevated values because rubber contains trace amounts of cadmium that are extracted as urine passing through the catheter.
