TIBC (Total Iron Binding Capacity)
TIBC reflects the total amount of iron that transferrin in blood can bind and serves as an indirect measure of transferrin concentration. It rises in iron deficiency as the body produces more transferrin in an effort to capture available iron, and falls in chronic disease, malnutrition, and iron overload. Used together with serum iron to calculate transferrin saturation.

Why It Matters
Reflects transferrin levels. Elevated in iron deficiency as body tries to capture more iron. Low in chronic disease. Used to calculate transferrin saturation.
