About HSL Advanced Diagnostics
HSL Advanced Diagnostics (HSL-AD) is a specialist clinical and research referral laboratory for targeted cancer diagnostics. It has been providing expert services to UCLH Hospitals since the early 1980s and to other hospitals around the UK and overseas since 1990, and is wholly owned and managed by Health Services Laboratories (HSL).
HSL-AD provides immunohistochemistry (ICH), in situ hybridisation (ISH) and molecular tissue diagnostics services. For ICH and ISH tests on formalin-fixed paraffin embedded tissue sections, we have one of the largest collections of antibodies and in situ probes in the UK. Our molecular pathology services include HPV genotyping and breast cancer profiling. In 2023, we performed 350,000 immunohistochemistry and 8,500 fluorescent in situ hybridisation tests for a wide spectrum of diseases.
These services are 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.
The laboratory's 39 scientific and administration staff are supported by a team of specialist Consultant Histopathologists.
