In iron deficiency anemia, which finding is typically increased?

In iron deficiency anemia, the body responds to low iron stores by increasing production of transferrin, the iron-binding protein. This upregulation raises the serum’s total iron-binding capacity, so TIBC is typically elevated. Even though iron is scarce, more binding sites are available to capture it, which is why the capacity goes up. In contrast, ferritin (stored iron) falls, transferrin saturation and serum iron fall, and red blood cells become microcytic with greater size variation ( RDW often increased). So the characteristic lab finding that is typically increased is the total iron-binding capacity.
