Her transferrin molekülü iki tane ferrik demiri güçlü bir şekilde bağlar.
Kan hacminde azalma nedir?
Kansızlık anlamına gelir. Kan hacmında, eritrosit sayısında, hemoglobin miktarında (hematokrit değerinde) azalmadır. Başlı başına bir hastalık değil, çeşitli hastalıklar sonucu oluşan bir bulgu (semptom)’dur. Anemi olgularında vücutta kansızlığa ilgili genel bulgular şekillenir.

What is transferrin and how is it made?
Transferrin has two iron-binding sites and is largely but not exclusively synthesized by the liver. There are over 20 genetic variants, largely single amino acid substitutions. Transferrin levels rise with iron deficiency and fall in cases of iron overload.
Transferrin receptor (TfR) is a disulphide-linked dimmer of two identical sub-units, 95 kDa each,9 found on most cells and especially those with a high requirement for iron, such as immature erythroid and malignant cells. Its function is to internalize absorbed iron into target cells.
Is transferrin a good indicator of iron deficiency anemia?
Transferrin is normally only about one-third saturated and is responsible for circadian variation in serum iron (peak in AM) due to variable activity of the reticuloendothelial system. Recent studies have indicated that the serum transferrin receptor levels can be used as an index of iron deficiency anemia.

Is the transferrin test approved by the FDA?​

This test has been cleared, approved, or is exempt by the US Food and Drug Administration and is used per manufacturer’s instructions. Performance characteristics were verified by Mayo Clinic in a manner consistent with CLIA requirements. Transferrin is a glycoprotein with a molecular weight of 79570 daltons.
