Reticulocyte count and reticulocyte percentage

Reticulocytes are transitional cells between late red blood cells and fully mature red blood cells, which are slightly larger than mature red blood cells and have a diameter of about 8 to 9.5 m. Due to the presence of basophilic RNA in the plasma, blue-green reticular structure can be seen in the cytoplasm after in vivo staining with the yellow tar blue, new methylene blue, and Nair blue sulfate staining solution, so it is named reticulate Red blood cells. After 24 to 48 hours of reticulocytes in the blood circulation, residual basophils are gradually eliminated and become mature red blood cells. Heilmyer divides reticulocytes into 5 types according to their different developmental stages.
