Whole blood manganese

The human body contains 12-18 mg of manganese. Manganese is mainly absorbed in the intestine, and is discharged into the feces through the liver with bile, and a small amount can be reabsorbed by the intestine. Manure excreted by the urine is less than 10% of the total discharge. Manganese accumulation in bone accounts for about 43% of the total body. Because manganese participates in the composition and activation of various enzymes, it is related to protein synthesis and improves lipid metabolism in atherosclerosis. Manganese can also promote the absorption and utilization of iron, participate in the synthesis of mucopolysaccharide (mucopolysaccharide is the main component of cartilage and bone tissue), and can resist oxidation and eliminate free radicals, and play a role in preventing cancer. Basic Information Specialist classification: growth and development check classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Tips: The determination of serum manganese in pregnant women can be increased. Normal value 73 to 255 μmol/L (0.4 to 1.4 μg/dl). Clinical significance Increased manganese poisoning, ischemic heart disease, myocardial infarction, acute and chronic hepatitis, necrotizing cirrhosis, rheumatoid arthritis, sun allergy, etc. High results may be diseases: manganese poisoning, liver cirrhosis considerations (1) The determination of serum manganese in pregnant women can be increased. (2) The distribution of manganese in the body is generally considered to be stable in manganese content, which reflects the level of human body more than blood manganese and urinary manganese. The content of the hair is more than the root of the hair, and is related to the color of the hair, usually black hair. Manganese content > yellow > white. The reference value is 1.2 to 2.1 μg/g. Inspection process (1) Atomic absorption spectrometry. (2) Emission spectrum analysis method. (3) Neutron activation analysis method. (4) X-ray fluorescence analysis. Not suitable for the crowd Generally no taboos. Adverse reactions and risks Dizziness or fainting: When blood is drawn, due to emotional overstress, fear, reflex caused by vagus nerve excitability, blood pressure drop, etc., the blood supply to the brain is insufficient to cause fainting or dizziness.
