Objective To analyze the clinical diagnostic value of multiple parameters in blood routine test for iron deficiency anemia (IDA). Methods A total of 168 patients diagnosed with IDA in our hospital from June 2023 to June 2025 were selected as the observation group, and 150 healthy physical examination patients during the same period were selected as the control group. Blood routine tests were conducted on all study subjects. Results The levels of Hb, MCV, MCH, and MCHC in the observation group were significantly lower than those in the control group, and the RDW level was higher (P<0.05). As the degree of anemia worsens, the decrease in MCV and MCH, as well as the increase in RDW, become more pronounced (P<0.05). Conclusion Blood routine examination has important screening and auxiliary diagnostic value for the clinical diagnosis of IDA.
