Which laboratory section typically performs tests on tissues and biopsy specimens?

The laboratory section that performs tests on tissues and biopsy specimens is Histology. In histology, trained professionals, often called histotechnologists or histotechnicians, prepare and examine tissue samples to identify and diagnose diseases. This process involves various techniques, including fixation, embedding, sectioning, and staining of tissue specimens, which allows pathologists to assess cellular structure and morphology.

Histology is essential for diagnosing cancers, inflammatory diseases, and other pathological conditions by providing microscopic images of the tissue architecture. The analysis performed in this section directly supports clinical decision-making in patient care.

In contrast, microbiology focuses on identifying and studying microorganisms such as bacteria, viruses, and fungi; chemistry deals with the analysis of body fluids for biochemical components; and hematology examines blood and its components to assess conditions related to blood cells. Each of these sections serves specific functions but does not specialize in the examination of tissue specimens like histology does.
