Which of the following are features of iron deficiency anemia except
Increased RDW
Decreased serum iron
Decreased TIBC
Decreased serum ferritin
Ref Harrison 19 th ed pg 627 The serum iron level repre- sents the amount of circulating iron bound to transferrin. The TIBC is an indirect measure of the circulating transferrin. The normal range for the serum iron is 50-150 mg/dL; the normal range for TIBC is 300-360 mg/dL. Transferrin saturation, which is normally 25-50%, is obtained by the following formula: serum iron x 100 / TIBC. Iron- deficiency states are associated with saturation levels below 20%. There is a diurnal variation in the serum iron.
