South West London Pathology 

Most pathology services are provided from the main ‘hub’ laboratory based at St George’s with ‘spoke’ Clinical Blood Science laboratories at the other hospital sites (Kingston Hospital NHS Foundation Trust and Croydon Health Services NHS Trust).  This ensures that essential clinical services such as A&E, theatres and obstetrics continue to receive the same level of pathology support.  It also enables local knowledge and clinical expertise to be retained within each Trust, but the whole partnership benefits from the larger scale and improved technology that can be provided through the establishment of a ‘hub’ laboratory.

Services included in South West London Pathology

The partnership officially started on 1 April 2014 and the following services are included:

  • Cellular Pathology – Cytology, Histology
  • Medical Microbiology
  • Clinical Blood Sciences – Haematology, Blood Transfusion, Protein Reference Unit and Immunology, Biochemistry
