Ratios of Red Cell Series to White Cell Series. In the final analysis bone marrow cytology allows a quantitative assessment only in relative terms. The important ratio of red precursor cells to white cells is 1 2 for men and 1 3 for women. Shifts towards erythropoiesis are seen in all regenerative anemias hemorrhagic anemia iron deficiency anemia vitamin deficiency anemia and hemolysis pseudopolycythemia Gaisbock syndrome and polycythemia also in rare pseudo-regenerative disorders such as sideroachrestic anemia and myelodysplasias. Shifts toward granulopoiesis are seen in all reactive processes infections tumor defense and in all malignant processes of the white cell series chronic myeloid leukemia acute leukoses .

In erythropoiesis polychromatic erythroblasts normally predominate. Proerythroblasts and basophilic erythroblasts only make up a small portion Table 4 . Here too a left shift indicates an increase in immature cell types and a right shift an increase in .
