Iron Total Binding Capacity, Total Blood Work Test

The Iron Total Binding Capacity (TIBC) test measures the total amount of iron that can be carried in the blood and the total amount of proteins available to bind with iron. Here are some reasons why you might consider getting an Iron TIBC test:

Iron deficiency anemia: Iron deficiency anemia occurs when the body does not have enough iron to produce hemoglobin, the protein in red blood cells that carries oxygen to the body’s tissues. The Iron TIBC test can help diagnose iron deficiency anemia by measuring the amount of iron that is available in the blood.

Hemochromatosis: Hemochromatosis is a genetic disorder that causes the body to absorb too much iron from food. Over time, excess iron can accumulate in organs such as the liver, heart, and pancreas, causing damage. The Iron TIBC test can help diagnose hemochromatosis by measuring the amount of iron that is bound to proteins in the blood.

Monitoring iron supplementation: Iron supplements are sometimes used to treat iron deficiency anemia. The Iron TIBC test can help monitor the effectiveness of iron supplements by measuring changes in the amount of iron that is available in the blood.

Evaluation of liver function: Iron is processed in the liver, and excess iron can damage the liver. The Iron TIBC test can be used to evaluate liver function by measuring the amount of iron that is bound to proteins in the blood.

In summary, the Iron TIBC test may be used to diagnose iron deficiency anemia and hemochromatosis, monitor the effectiveness of iron supplementation, and evaluate liver function. If you have symptoms of iron deficiency or excess, or if you are being treated with iron supplements, your healthcare provider may recommend an Iron TIBC test as part of your care.
