Pathology Department
General introduction
Pathology is an integral part of the clinical support services at the Trust and performs tests which support care and treatment in hospital and community settings. The department is divided into four sections:
• Biochemistry (including Immunology and point of care testing)
• Haematology and Blood Transfusion
• Histopathology and Cytology
• Microbiology (including virology and molecular)
From the 1 April 2026, Warrington and Halton Hospitals pathology services now operate under the management of Mersey West Lancashire Teaching Hospital NHS Trust. Pathology services remain sited at Warrington and Halton Hospitals. It is important to note there are no changes to how you access tests or receive results- services will continue as normal.
Information for GPs, health professionals and patients with guidance on how to complete and submit tests to Pathology is available within the Lab User’s Handbook (GP edition) PDF [3.2MB]
