Histopathological Techniques and Their Importance in Diagnosis
Histopathology, the microscopic examination of tissue to study the manifestations of disease, plays a crucial role in medical diagnostics . Through various staining and visualization techniques, pathologists can accurately diagnose a wide array of diseases, from infections to cancers. Each histopathological method provides unique insights, making it indispensable in understanding disease mechanisms and guiding patient treatment. What is Histopathology ? Histopathology involves the preparation, staining, and examination of tissue samples under a microscope . The tissue can be obtained from a biopsy, surgical resection, or post-mortem examination. By evaluating the structural changes within cells and tissues, pathologists can identify abnormalities and make definitive diagnoses. The process typically begins with fixation to preserve tissue integrity, followed by embedding , sectioning , and staining . Once stained, the tissue is examined under a microscope to detect disease pa
