Serum Iron or TIBC

Pre test Information : No Special Preparation Needed

A total iron-binding capacity test is a blood test that determines how much transferrin in your blood binds to iron, which indicates how well iron works in your body.

Transferrin is a protein produced by your liver that attaches to or binds to iron in your blood. Once iron is bound to transferrin, it travels to your bone marrow to be used in the formation of red blood cells and hemoglobin, a protein that aids in the transport of oxygen.

Iron-binding capacity is classified into two types: unsaturated iron-binding capacity and total iron-binding capacity.

Iron-binding capacity that is unsaturated (UIBC). This determines how much transferrin has not yet been bound to iron.

Iron-binding capacity total (TIBC). This represents the total amount of iron in your blood as well as the UIBC.

Why Is a TIBC Test Required?

Iron is an important mineral for your health, but it is lost through sweat, period blood, and the shedding of skin and blood cells. Because your body does not have a way to stop iron loss, it tightly controls how it is absorbed.

Too little iron can make you sick, but too much can be dangerous. Extra iron will be deposited in your heart, liver, brain, and endocrine glands such as your thyroid. This will harm your organs and could result in heart failure and brain damage.

If you show signs of high or low iron, your doctor will order a TIBC test. Among these symptoms are:

Tiredness
Weakness: Pale skin
Constantly feeling cold
Frequently becoming ill
Tongue enlargement
Children's brain development issues

Too much iron can lead to:

Tiredness
Weakness
stomach ache
Joint discomfort

During pregnancy, your doctor may also check your TIBC because you require more iron.
