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.
