Abstract Objective：To evaluate the clinical value of four RBC parameters for diagnosis iron deficiency anemia. Method：A total of 54 iron deficiency anemia patients and 54 same period healthy as control from January 2012 to March 2014 for this study， four red blood cell parameters were measured and peripheral blood erythrocyte morphological staining microscopy.Result：MCH，MCHC，MCV significantly lower than in healthy controls group，but RDW was significantly higher； 2 cases（3.70%） were negative，52 cases（ 96.30%） were positive； based on peripheral blood smear Wright -Giemsa stain results， 54 cases（ 100%） of patients were all positive. Conclusion：Four RBC parameters has high diagnostic accuracy for iron deficiency anemia， can be used as an important indicator for preliminary screening iron deficiency anemia.
