HSL Advanced Diagnostics (HSL-AD) is a specialist clinical and research referral laboratory for targeted cancer diagnostics.

Modern personalised cancer treatments depend upon an accurate characterisation of the disease, and HSL-AD provides a leading service, nationally and internationally, for immunohistochemistry, in situ and molecular pathology tissue diagnostics.

The service is available on a permanent or temporary basis to all laboratories, pathologists, and oncologists – whether they require a complete immunohistochemistry, in situ or molecular service, or just to complement their own local testing protocols with additional, specific biomarkers.

HSL-AD is supported by a team of specialist Consultant Histopathologists, and is a UKAS Accredited Medical Laboratory, No. 9007.
