Red cell count (RBC), hemoglobin concentration (Hb) and hematocrit (Ht) are frequently used as the indices of anemia. The author examined the relationships between these three factors by using medical checkup data of some 34, 000 men and women. A strong relationship was observed between Hb and Ht, which guaranteed the accuracy of their mutual inferences. No such strong relationship was found between RBC and Hb and between RBC and Ht. The popular view, therefore, was supported that alternative measurement of Hb or Ht is sufficient for the screening of anemia but that single measurement of RBC would not be enough for that purpose. Furthemore, in the case of women approximately from 30 to 50 years of ase some effects were also noticed which were supposed to be caused by an increase of the individual differences in mean corpuscular volume (MCV).
