Several techniques are employed in histopathology to gather data essential for epidemiological studies:
Light Microscopy: The most common technique, which involves staining tissues and examining them under a microscope to identify abnormalities. Immunohistochemistry: Uses antibodies to detect specific antigens in tissues, helping to identify infectious agents or cancer markers. Electron Microscopy: Provides detailed images of tissue ultrastructure, essential for understanding cellular changes at a higher resolution. Molecular Pathology: Involves techniques like PCR and sequencing to detect genetic changes and pathogens at the molecular level.
