About Our Manganese, Blood Test
Note: Fasting is not required for this test.
Manganese is a mineral that plays a key role in forming connective tissue, sex hormones, making blood clotting factors, bone health, wound healing and central nervous system function. Manganese is also essential for the absorption of calcium, as well as glucose regulation, carbohydrate, fat, cholesterol and amino acid metabolism. This blood test is used to monitor manganese levels or manganese exposure.
Chronic exposure to manganese (as in industrial settings) may cause effects on the central nervous system.
Toxic exposure may occur from dry cells, fungicide (maneb), and in the steel or chemical industries. Manganese is present in the coloring agents for glass and soap, in paints, varnish and enamel, and in linoleum.
It is used in the manufacturing of chlorine gas and in lead-free gasoline. Industrial manganese poisoning has been recognized since 1837.
This test is also used in following individualize manganese-dosing in long-term parenteral nutrition and to follow the success of chelation therapy with para-aminosalicylate sodium in manganism.
Manganese levels that are too high can lead to:
- Mouth and throat dryness
- Muscle pains/cramps
- Hearing loss/impairment
- Personality change
Deficient manganese levels can lead to:
- Impaired glucose tolerance
- Altered carbohydrate and fat metabolism
- Skeletal abnormalities/Loss of mineralization in bones
- Rashes on skin
- Iron-deficiency anemia
- Increased blood calcium levels
- Elevated phosphorus and alkaline phosphatase levels
- Nausea and vomiting
Major dietary sources of manganese include:
- Dark, leafy greens
- Sweet potatoes
- Nuts and seeds
