May be useful as a reasonable indicator of recent, active exposure and provides a modest indicator for distinguishing exposed from nonexposed individuals. Not recommended for the assessment of manganese body stores. Manganese, Whole Blood (0099272) is recommended for monitoring potential accumulation with TPN.

Elevated results may be due to skin or collection-related contamination, including the use of a noncertified metal-free collection/transport tube. If contamination concerns exist due to elevated levels of serum manganese, confirmation with a second specimen collected in a certified metal-free tube is recommended.
Less than 5 percent of manganese present in circulation resides in the serum.
