Detecting exposure to cadmium, a toxic heavy metal, as a part of occupational monitoring
Triple Quadrupole Inductively Coupled Plasma Mass Spectrometry (ICP-MS/MS)
Cd (Cadmium)
Cadmium (Cd)
Whole blood
Patient Preparation: High concentrations of gadolinium and iodine are known to potentially interfere with most inductively coupled plasma mass spectrometry-based metal tests. If either gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.
Supplies: Metal Free B-D Tube (EDTA), 6 mL (T183)
Container/Tube: Royal blue top (EDTA) Vacutainer plastic trace element blood collection tube
Specimen Volume: Full tube
Collection Instructions:
1. See Metals Analysis Specimen Collection and Transport for complete instructions.
2. Send whole blood specimen in original collection tube. Do not aliquot.

Detecting exposure to cadmium, a toxic heavy metal, as a part of occupational monitoring
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.
< 5.0 mcg/L
Reference values apply to all ages.
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.
