[The quantitative erythrogram and the possibiilty of its clinical and experimental use]

Quantitative erythrogram, i. e. the per cent distribution of the cells of different shapes into 5 groups (discocytes, stomatocytes, echinocytes, poikilo- and schizocytes, hemolytic forms) is recommended to be taken into consideration when estimating the red cell transformation in clinical and experimental studies. The classifying morphologic signs of about forty erythrocyte forms are described, and examples of the quantitative erythrogram use are given.
