Transferrin

Transferrin is a protein in the blood that plays a crucial role in iron transport. It binds to iron, which is essential for producing red blood cells and for various cellular functions. Transferrin helps move iron from the intestines, where it is absorbed, to the tissues that need it, such as the liver and bone marrow. By regulating iron levels, transferrin helps prevent both iron deficiency and excess, which can cause health issues. Its level in the blood can be measured to assess iron status and diagnose conditions like anemia or iron overload disorders.
