Clinical Biochemistry is involved in diagnosis, monitoring and treatment of disease through analysis of bodily fluids such as blood, urine and CSF. The results of biochemical tests are vital in selecting the most appropriate management pathways, and providing the best possible care for patients.


The Biochemistry Department offers a comprehensive service for its users, including analysis and interpretation of routinely requested tests; and a number of specialist services. The Department receives over 6000 requests and produces approximately 25 000 results during a normal working day.

The majority of tests are performed using automated analysers, although for some tests, a significant manual component is necessary. In addition, the Department is able to facilitate referral of samples to specialist laboratories for analysis.
