Special Info

Patient Prep: Diet, medication and nutritional supplements may introduce interfering substances. Patients should be encouraged to discontinue nutritional supplements, vitamins, minerals and non-essential over-the-counter medications (upon the advice of their physician). Unacceptable conditions: Plasma. Hemolyzed specimens. Separator tubes or EDTA (royal blue) tubes. Specimens that are not separated from the red cells, or clot, within 2 hours. Specimens transported in tubes other than specified. This test is New York DOH approved.

Clinical Info

Less than 5% of manganese present in circulation resides in the serum. 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.
