Transferrin (Siderophilin, Transferrin)

The interpretation of the research results contains information for the attending physician and is not a diagnosis. The information in this section cannot be used for self-diagnosis and self-medication. An accurate diagnosis is made by a doctor using both the results of this examination and the necessary information from other sources: anamnesis, results of other examinations, etc. Units of measurement: g/l. Alternative units: mg/dl. Conversion factors: mg/dl x 0.01 => g/l. When serum iron and transferrin are simultaneously determined, an estimated indicator is given in the response – % saturation of transferrin. Reference values Age Women, tranferrin, g/l Men, tranferrin, g/l 1 day - 12 months 1,33 - 3,32 1,33 - 3,32 12 months - 5 years 2,04 - 3,66 2,04 - 3,66 5-10 years old 1,77 - 3,71 2,17 - 3,21 10 - 14 years old 2,00 - 3,67 1,81 - 3,53 14 - 20 years old 1,93 - 4,21 1,83 - 3,63 20 - 60 years old 2,5 - 3,8 2,15 - 3,66 60 - 90 years old 1,9 - 3,75 1,9 - 3,75 > 90 years old 1,86 - 3,47 1,86 - 3,47 Interpretation of the results of the Transferrin study Increasing values Iron deficiency (an increase in the level may precede the development of anemia for several days or months). Taking estrogens and oral contraceptives. Lowering the values Chronic inflammatory processes. Hemochromatosis. Cirrhosis of the liver. Protein loss in burns, nephrotic syndrome and gastroenteropathies (malabsorption syndrome). Malignant tumors. Taking androgens and glucocorticoids. Hereditary atransferrinemia (rare). Multiple blood transfusions (overload of the body with iron). Conditions accompanied by increased oncotic pressure (multiple myeloma, hepatocellular disease). Note. If there are studies No. 48 Serum Iron and No. 50 Transferrin in the application at the same time, the % saturation index of transferrin with iron is additionally calculated. Reference limits of % transferrin saturation: under 14 years: 10-39%; from 14 years and older: 16-50%.
