Pathology

Pathology is the study and diagnosis of disease through examination of organs, tissues, bodily fluids, and whole bodies (autopsies). The term also encompasses the related scientific study of disease processes, called general pathology.

The pathology department is a clinical support service, providing diagnostic and clinical advice to surgeons and clinicians within the Trust, and to local GPs.

The pathology department at Epsom and St Helier University Hospitals NHS Trust is one of the largest non-medical school laboratories in the country. We are registered with Clinical Pathology Accreditation (UK) Ltd.,  where you can check the current accreditation status of our individual laboratories.

We are also accredited to train biomedical scientists, clinical scientists and junior doctors.

Our quality team ensures the whole department complies with quality management systems and meets the requirements set by regulators and accreditors.

Here you can find information for patients coming for various tests, and for healthcare professionals, including a searchable test directory and guidance on completion of request forms and labelling of samples.
