Manganese, Whole Blood
Also known as: MANG WB
Use
The Manganese, Whole Blood test is useful as a reasonable indicator of recent, active exposure to manganese and provides a modest indicator for distinguishing exposed from nonexposed individuals. It is recommended for monitoring potential accumulation with total parenteral nutrition (TPN). However, it is not recommended for detecting long-term, low-dose manganese exposure. In such cases, Manganese, RBC should be referred to.
Special Instructions
Patient should be encouraged to discontinue nutritional supplements, vitamins, minerals, and non-essential over-the-counter medications upon the advice of their physician to avoid interference with the test results.
Limitations
Elevated results may be due to contamination from skin or the collection process, including the use of tubes that are not certified to be trace element free. If a high result is suspected to be due to contamination, confirmation with a second specimen collected in a certified trace element-free tube is recommended.
