Special staining procedures such as AFB (acid-fast bacilli), Wade Fite, GMS (Grocott’s Methenamine Silver), Gram, Warthin-Starry, and Oil Red O are specialized histopathology staining techniques that color specific cellular components, targets, or pathogens. They deferentially highlight bacteria, fungi, mycobacteria, parasites, or lipid deposits in tissue sections, provide detailed information beyond routine histological features, and enhance the accuracy of disease diagnosis.
