Chemical pathologists are qualified doctors who combine practical laboratory and clinical skills. They use biochemical laboratory tests to diagnose disease and to manage patients. Chemical pathologists have a detailed understanding of biochemical processes and changes that occur in disease.

General pathology describes a complex and broad field that involves the study of the mechanisms behind cell and tissue injury, as well as understanding how the body responds to and repairs injury.

Microbiology is the study of microscopic organisms, such as bacteria, viruses, archaea, fungi and protozoa. This discipline includes fundamental research on the biochemistry, physiology, cell biology, ecology, evolution and clinical aspects of microorganisms, including the host response to these agents.

Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell’s functions and maintenance.
