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.
