The measurement of the concentration of hemoglobin or erythrocytes in the peripheral blood is probably one of the most widely employed laboratory aids in clinical medicine. Interpretation of these measurements is based upon widely used standards for normal values which were obtained by statistical studies of large groups of persons in many geographical areas.1 The impression of the existence of anemia or polycythemia is given when values obtained are respectively lower or higher than those accepted standards.An investigation of the relationship between the peripheral blood cell counts and the total body red cell volume was undertaken in a variety of clinical states. The present study deals with this correlation in a group of normal subjects and in patients with elevated erythrocyte values.
The subjects studied were patients on the wards or attending the hematology clinic at Kings County Hospital. They were selected on the basis of
