Which statement is true regarding reticulocyte staining?

The key idea is how reticulocytes are visualized and counted. Reticulocytes still contain residual ribosomal RNA, which forms a fine mesh that can be seen only when stained with supravital dyes. Dyes like methylene blue or brilliant cresyl blue precipitate the RNA, creating the characteristic network that identifies reticulocytes under light microscopy. Because of this, the reticular network is best revealed with supravital staining, making it possible to count reticulocytes as a proportion of total red cells. A standard Wright stain does not highlight the RNA network, so reticulocytes cannot be reliably identified with Wright staining alone. Staining is essential for their visualization and counting; without such staining, reticulocytes would be indistinguishable from mature erythrocytes.
