The Iron Total and Total Iron Binding Capacity (TIBC) Test measures iron levels in blood along with the blood’s ability to transport iron. It helps diagnose iron deficiency anemia, iron overload (hemochromatosis), and monitor nutritional or chronic health conditions. Low iron or high TIBC may indicate anemia, while high iron or low TIBC can suggest overload. Doctors use this test to evaluate fatigue, weakness, or other symptoms linked to iron and metabolic health.
