HSL Rapid Response Laboratories: Specialist services

Lipid Clinics (at Royal Free London only)

The department has a long-standing interest in the management of lipid disorders including familial hypercholesterolaemia. The department hosts a nationally recognised specialist clinical and laboratory service for the management of inherited lipoprotein disorders as well as complex lipoprotein abnormalities and their investigation. It is renowned for providing an integrated service for the management of familial hypercholesterolaemia, with cascade testing supported by clinical nurse specialists. There is also a paediatric service.


Supra Regional Assay Service (SAS) for Cardiovascular Biomarkers (at Royal Free London only)

The SAS service for cardiovascular biomarkers supports the investigation of complex lipoprotein abnormalities. Senior clinicians for the SAS centre can be contacted for advice on appropriate investigations.

The centre also supports research and development through a research laboratory. We work with several collaborators both nationally and internationally on projects related to cardiac biomarkers and lipoprotein metabolism.

Any R and D enquiries should be directed to HSL R&D department contact Siddra Noureen at siddra.noureen@tdlpathology.com. Senior staff are always happy to discuss and advise on the appropriate choice of tests as well as providing clinical advice.

A pre- produced specimen must be brought to Pathology Specimen Reception at the appointed time. It must be collected directly into a pre-weighed specimen container (provided from Specimen Reception) and maintained at body temperature (keep in trouser pocket).

The specimen must be delivered to the laboratory within 1 hour of collection.
