Which of the following finding are there in iron deficiency anemia?

The diagnosis of iron deficiency anemia ultimately rests on laboratory studies. The serum iron and ferritin are low, and the total plasma iron-binding capacity (reflecting elevated transferrin levels) is high. Low serum iron with increased ironbinding capacity results in a reduction of transferrin saturation to below 15%. Reduced iron stores inhibit hepcidin synthesis, and its serum levels fall.
