Abstract
Characteristics of several parametrs of red cells were investigated for aged patients with iron deficiency state using a new automated blood cell counter, Model H-1. The patients showed decreased red cell production in spite of low grade of iron deficiency. RDW (red cell distridution width) showed a high correlation to MCV, and HDW (hemoglobin concentration distribution width) showed higher correlation to MCH than to MCHC. Both RDW and HDW showed iron deficiency state, and the aged showed lower RDW and HDW. Samples after blood transfusions showed two peaks on the hemoglobin distribution curve. We concluded that the above-mentioned parameters would be available for clinical purpose.
