Histological examination involves the analysis of tissue samples under a microscope to identify abnormalities at the cellular level. Techniques such as Hematoxylin and Eosin (H&E) staining, immunohistochemistry, and special stains are employed to visualize structural changes, inflammatory infiltrates, and other pathological features. For example, in cases of liver damage, histology might reveal hepatocyte ballooning, steatosis, and fibrosis.
