Unbound Iron Binding Capacity (UIBC)
The Unbound Iron Binding Capacity (UIBC) test evaluates the portion of transferrin that is not yet bound to iron in the bloodstream. Transferrin is a protein responsible for transporting iron throughout the body. The UIBC value reflects the available binding sites on transferrin and helps determine how much more iron can be carried in the blood.
This test is commonly used along with serum iron and total iron binding capacity (TIBC) to assess iron metabolism. It plays an important role in diagnosing conditions such as iron deficiency anemia and iron overload disorders.
Low UIBC levels may indicate higher iron levels in the body, while elevated UIBC levels are often associated with iron deficiency. The test helps clinicians better understand iron balance and guides appropriate treatment decisions.
Test Recommended For
- Individuals with symptoms of anemia (fatigue, weakness, pale skin)
- Patients with suspected iron deficiency
- Individuals with suspected iron overload disorders
- Patients undergoing iron profile evaluation
- Monitoring response to iron therapy
