The Total Iron Binding Capacity (TIBC) test assesses iron-related conditions, including iron deficiency anemia, a condition that can lead to symptoms such as fatigue, weakness, pale skin, shortness of breath, and brittle nails. Iron overload disorders, which may have symptoms like joint pain, abdominal pain, and fatigue, can also be evaluated through this test. TIBC indirectly measures transferrin, an essential liver-produced protein responsible for iron transport in the blood. By calculating iron saturation, healthcare providers can gain insights into the body’s iron metabolism. This test aids in diagnosing and monitoring iron-related disorders and anemias, as well as monitoring the effectiveness of treatments aimed at restoring iron balance in the body.
