Histotechnologists perform complex histological procedures, optimising tissue processing, microtomy, and advanced staining for accurate pathological interpretation. They develop and validate special stains, immunohistochemistry panels, and sometimes in situ hybridisation protocols. Responsibilities include troubleshooting artefacts, maintaining high-quality slide preparation, participating in laboratory quality programs, and assisting in digital pathology workflows. They collaborate closely with pathologists and may support teaching and research projects. Work is concentrated in tertiary hospitals, cancer centres, academic medical centres, and specialised pathology laboratories. Demand is reinforced by rising cancer incidence, precision oncology, and the growth of immunohistochemistry and molecular–pathology interfaces.
