Ordering Recommendation

Useful as a reasonable indicator of recent, active exposure and provides a modest indicator for distinguishing exposed from nonexposed individuals. Recommended for monitoring potential accumulation with TPN. Not recommended for detecting long-term, low-dose manganese exposure, refer to Manganese, RBC (2007254).
