Histochemical Staining for Pigments and Minerals

This topic covers the histochemical techniques used for the identification and demonstration of pigments and minerals in tissue samples, a fundamental skill in diagnostic histopathology and clinical laboratory science in Zambia. Students will learn to distinguish between artifact, exogenous, and endogenous pigments, as well as the detection of minerals such as calcium, iron, and copper. Techniques including Prussian Blue, Turnbull's Blue, Fontana-Masson, Von Kossa, and Fouchet's are explored in depth. For Zambian university and college students pursuing diplomas or degrees in medical laboratory science or pathology, mastery of these stains is critical for accurate tissue diagnosis, essential for laboratory management and forensic science applications. The topic prepares learners for professional examinations and careers in hospital laboratories, research institutions, and public health, ensuring they can contribute effectively to Zambia's healthcare system by supporting accurate disease identification and treatment planning.
