Clinical Information

The toxicity of cadmium resembles the other heavy metals (arsenic, mercury, and lead) in that it attacks the kidney; renal 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 of organic-based paints without use of 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.

Method Name

Inductively Coupled Plasma-Mass Spectrometry (ICP-MS)

Report Available

1 to 2 days

Reporting Name

Cadmium, B

Reference Values

<5.0 ng/mL

Reference values apply to all ages.

Interpretation

Normal blood cadmium is <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.

Method Description

Cadmium (Cd)is analyzed by inductively coupled plasma-mass spectrometry (ICP-MS) in kinetic energy discrimination (KED) mode using helium as a non-reactive gas to collide with polyatomic interferences such as argon chloride (ArCl). Internal standard used is rhodium (Rh). A salt matrix calibration is used.(Unpublished Mayo method)

Day(s) Performed

Monday through Saturday
