Test Details

Synonyms

  • Mn, Blood

Use

Monitor manganese exposure

Limitations

In evaluating toxicity, the serum level may have returned to normal while the neurological damage persists. In evaluating possible deficiency states, the human deficiency syndrome is poorly defined, making interpretation difficult. Levels are reportedly reduced mildly in epilepsy, and raised in hepatitis or jaundice. Manganese levels are 60% lower than normal in hemodialysis patients.

This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration.

Methodology

Inductively-coupled plasma/mass spectrometry (ICP/MS)

Reference Interval

8.0−18.7 μg/L

Additional Information

Toxic exposure may occur from dry cells, fungicide (maneb), and in the steel or chemical industries. Manganese is present in the coloring agents for glass and soap, in paints, varnish and enamel, and in linoleum. It is used in the manufacture of chlorine gas and in lead-free gasoline. Industrial manganese poisoning has been recognized since 1837.
