Wright Staining Solution is widely used in clinical laboratories for staining blood and bone marrow smears. It enables clear differentiation of blood cell types by coloring cellular components such as nuclei, cytoplasm, and granules in distinct hues. This staining is essential for performing differential white blood cell counts, identifying abnormal cells, and diagnosing conditions like anemia, infections, and leukemia. The stain is particularly effective in highlighting morphological details in peripheral blood films, making it a standard tool in hematology. It is also used in veterinary medicine for similar diagnostic purposes.
