Chemical Pathology

Our chemical pathologists analyse chemicals in our body fluids and tissues to help diagnose and manage disease. They play a unique dual-role of doctor-scientist, looking at changes in human body chemistry for screening, diagnosis, prognosis and management.

About our Chemical Pathology service

Chemical pathologists have complex clinical and laboratory skills needed to perform biochemical tests on human body fluids and tissues.

They examine blood, tissues and urine, and other body fluids such as cerebrospinal fluid.

Changes in enzymes, proteins, electrolytes and other substances in these fluids and tissues give clues they need to diagnose illness and recommend patient care and treatment.
