Serum iron TIBC

Serum iron TIBC is a blood test that measure the total amount of iron in your blood. Iron is a very important element in our body and in a person whose weight is 70 kg, there is 4.00 to 4.5 g iron in it and it is found in the following places in the body.

There are many factors that affect the absorption of iron. It is in the form of iron ferrous. Iron exists in two forms in our body.

  1. Ferrous Form
  2. Ferric Form

Ferrous iron is found in oxyhemoglobin and reduced hemoglobin while ferritin (Fe3+) is stored and binds to hemosiderin and a transferring protein. Iron is absorbed by intestinal mucosal cells in the ferrous state and is in divalent form. Iron is oxidized and Ferritin is formed which is the storage form of iron. Iron is needed in our body. It is released into the bloodstream and moves through our body along with a transport protein called transferrin. And iron is released from it whenever our body needs iron, this iron is transferred to bone marrow and other tissues etc. where it is used in myoglobin. Also in cytochromes and in hemoglobin. If iron is needed in our body, it is stored in our body and used when needed.

Normal results of iron testing may be different for men, women, and children. Iron and TIBC are measured in micrograms per deciliter (mcg/dL). Normal results for iron are:

  • 80 to 180 mcg/dL for men
  • 50 to 170 mcg/dL for women
  • 50 to 120 mcg/dL for children
