[Value of measurement of the red cell volume in polyglobulia and anemia. Expression of the results].

As an introduction to the following paper, devoted to the clinical usefulness of the measurement of the red cell volume in polycythemic and anemic states, the mode of expression of the experimental results of red cell volume is discussed. The comparison between the several equations, which try to give a normal value, by taking into account the height and weight of the subjects shows that the differences are very slight between the several estimations. On the contrary, the expression of the red cell volume as a function of the weight only can be the cause of misinterpretation of the measure of the red cell volume, in fat and thin people.
