Special Instructions
Method Name
Triple-Quadrupole Inductively Coupled Plasma-Mass Spectrometry (ICP-MS/MS)
Reporting Name
Manganese, SSpecimen Type
SerumSpecimen Required
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

Reference Values
0-17 years: Not established
≥18 years: 0.4-0.9 ng/mL
Interpretation
Serum manganese results above the reference values suggest recent exposure. Serum concentrations in combination with brain magnetic resonance imaging scans and neurological assessment may be used to detect excessive exposure.
