Transferrin, Serum

Serum transferrin is used to control chronic iron overload conditions such as hereditary hemochromatosis.

More information

Transferrin, or otherwise, siderophyllin, belongs to the beta globulins and is a glycoprotein with a relatively short (about 7 days) half-life. It is formed in the liver and transports iron from the intestinal mucosa to iron storage sites and hemoglobin synthesis sites (bone, muscle, erythrocytes, lymphocytes). Transferrin allows the transfer of iron by binding to the transferrin receptors.

Transferrin is capable of binding more than its weight to iron (1 g of transferrin can carry 1.43 g of iron). Normally, iron saturation (transferrin saturation) is between 20% and 45%. Due to the short half-life, its values ​​decrease more rapidly in malnutrition than albumin.

Possible Interpretations of Pathological Values
 
  • Increase: Iron deficiency anemia with normal protein levels, pregnancy. Medications: Carbamazepine, estrogen, oral contraceptives
  • Decrease: Congenital absence of transferrin (hereditary atansferrinemia), haemolytic anemia, hepatic disease (acquired), inflammation (chronic), iron overload, low iron in combination with malnutrition, neoplasia, neovirostasis, proteinuria. Medications: Cortisone

 

 

Important Note

Laboratory test results are the most important parameter for the diagnosis and monitoring of all pathological conditions. 70%-80% of diagnostic decisions are based on laboratory tests. Correct interpretation of laboratory results allows a doctor to distinguish "healthy" from "diseased".

Laboratory test results should not be interpreted from the numerical result of a single analysis. Test results should be interpreted in relation to each individual case and family history, clinical findings and the results of other laboratory tests and information. Your personal physician should explain the importance of your test results.

At Diagnostiki Athinon we answer any questions you may have about the test you perform in our laboratory and we contact your doctor to get the best possible medical care.
