Manganese, Serum
Use
Manganese (Mn) is a trace essential element important for various industrial uses such as steel production, where it improves hardness, stiffness, and strength. It is naturally found in the environment and can be a major source of exposure via inhalation and ingestion, particularly in vegetarians or heavy tea drinkers with diets high in grains, beans, and nuts. Mn toxicity can cause serious symptoms affecting neurological function, progressing through stages of malaise, psychological disturbances, and motor function impairments. This test is useful for monitoring manganese exposure using serum specimens.
Special Instructions
Not provided.
Limitations
High concentrations of gadolinium and iodine may interfere with ICP-MS based metal tests. Specimens should not be collected within 96 hours following contrast media administration. Potential for contamination necessitates the use of metal-free collection and handling. Results may be influenced by environmental exposure leading to contamination.
