Figure 7.5B. Image of a blood smear fixed and stained with crezyl blue showing erythrocytes (E) in various shades of blue-green.

The smear also contains cells called reticulocytes (R), that is, erythrocytes containing basophilic and granulated networks. These networks are composed of precipitated ribosomes.

These reticulocytes, which are immature erythrocytes, compose 1% to 2% of the erythrocyte population. Higher percentages of these reticulocytes in the blood indicate an increased production of red blood cells in stimulated bone marrow under the influence of erythropoietin, which is produced in a hemorrhage.

Stain: Wright-Giemsa (7.5A); Crezyl blue (7.5B)
