<prompt> Which of the following findings is diagnostic of iron deficiency anemia -Increased TIBC, decreased serum ferritinDecreased TIBC, decreased serum ferritinIncreased TIBC, increased serum ferritinDecreased TIBC, increased serm ferritin  <response>: In the development of anemia ,firstly storage ironferritin depletion occurs during which iron reserves are lost without compromise of the iron supply for erythropoiesis.So serum ferritin decreases.TIBC is high and rises to give less than 10 saturation normal 30.
