Final answer:
Total iron-binding capacity (TIBC) measures the serum iron transporting capacity in the blood. It represents the maximum amount of iron that can be bound to transferrin, a blood protein responsible for transporting iron.
Step-by-step explanation:
Total iron-binding capacity (TIBC) is a measure of the serum iron transporting capacity in the blood. It represents the maximum amount of iron that can be bound to transferrin, a blood protein responsible for transporting iron throughout the body. TIBC levels are a useful diagnostic tool in assessing iron deficiency or iron overload conditions.
