Wright's stain is widely used in medical and clinical laboratories for staining blood smears to facilitate the microscopic examination of blood cells. It is particularly valuable in hematology for differentiating and identifying various types of white blood cells, red blood cells, and platelets. The stain helps in diagnosing conditions such as anemia, infections, and blood disorders by highlighting cellular structures and abnormalities. It is also employed in bone marrow examination to assess cell morphology and detect malignancies like leukemia. Additionally, Wright's stain is used in research settings to study blood-related diseases and cellular responses. Its ability to provide clear, detailed staining makes it a critical tool in both diagnostic and investigative pathology.
