| Additional information | Manganese is an essential trace metal. Over 95% of manganese in blood is protein bound and therefore whole blood levels are higher than those derived from serum. Toxicity that can result from excessive exposure can cause serious organ damage. Symptoms include Parkinsonian-like tremor and gait disturbances. manganese is excreted in bile therefore patients with hepatic dysfunction/cholestasis and receiving manganese in TPN may be at increased risk for toxicity. To convert µg/L to nmol/L (SI units) multiply by 18.2. |
