Useful For
Detecting exposure to cadmium, a toxic heavy metal
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. In addition, another common source of cadmium exposure is tobacco smoke.
Interpretation
Normal blood cadmium is less than 5.0 ng/mL, with most results in the range of 0.5 to 2.0 ng/mL.
Acute toxicity will be observed when the blood level exceeds 50 ng/mL.
Cautions
No significant cautionary statements
