Reporting Name
Cadmium Occupational Monitor, BUseful For
Detecting exposure to cadmium, a toxic heavy metal, as a part of occupational monitoring
Method Name
Triple Quadrupole Inductively Coupled Plasma Mass Spectrometry (ICP-MS/MS)

Test Classification
This test was developed and its performance characteristics determined by Mayo Clinic in a manner consistent with CLIA requirements. It has not been cleared or approved by the US Food and Drug Administration.Clinical Information
The toxicity of cadmium resembles the other heavy metals (arsenic, mercury, and lead) in that it attacks the kidney; kidney dysfunction with proteinuria with slow onset (over a period of years) is the typical presentation.
Breathing the fumes of cadmium vapors leads to nasal epithelial deterioration and pulmonary congestion resembling chronic emphysema.
The most common source of chronic exposure comes from spray painting organic-based paints without a protective breathing apparatus; auto repair mechanics represent a susceptible group for cadmium toxicity. Tobacco smoke is another common source of cadmium exposure.
Interpretation
Normal blood cadmium is less than 5.0 mcg/L, with most results in the range of 0.5 to 2.0 mcg/L.
Acute toxicity will be observed when the blood level exceeds 50 mcg/L.
Cautions
No significant cautionary statements
