Total Iron Binding Capacity (TIBC)

Total Iron Binding Capacity (TIBC) is a blood test that measures how well transferrin, a protein that carries iron, can bind to iron. It indicates the amount of iron that can be transported in the blood. High TIBC levels often suggest iron deficiency, as the body produces more transferrin to capture available iron. Conversely, low TIBC levels can indicate adequate iron stores or conditions like liver disease. TIBC is useful in diagnosing and managing conditions related to iron metabolism, helping healthcare professionals understand a patient's iron status effectively.
