Total Iron-Binding Capacity Test - Total Iron-Binding Capacity (TIBC) Test

Total iron-binding capacity (TIBC) analysis measures the total amount of iron that can bind to transferrin in the blood serum. TIBC indirectly reflects the level of transferrin produced in the liver. It provides an estimate of the number of "available seats" for iron in the blood, indicating whether these seats are already occupied or remain vacant. TIBC is used in conjunction with iron measurement to calculate the transferrin saturation ratio, a crucial indicator in the diagnosis of iron metabolism disorders.
