The HSL Partnership

Health Services Laboratories (HSL) is a partnership between The Doctors Laboratory, Royal Free London NHS Foundation Trust (the Royal Free London) and University College London Hospitals NHS Foundation Trust (UCLH)


The Doctors Laboratory

The Doctors Laboratory (TDL) was established in 1987. TDL is the largest independent provider of clinical pathology services in the UK, with two hub laboratories in central London and Manchester. The two hubs support TDL’s national network of laboratories throughout the UK. Their pathology services extend to hospitals, laboratories and clinical practice in the NHS and Independent Healthcare Sector. In 2003 TDL partnered with University College London Hospitals NHS Foundation Trust (UCLH), and in 2015, formed Health Services Laboratories (HSL) with UCLH and Royal Free London. TDL is owned by Sonic Healthcare Ltd, an Australian clinical diagnostics organisation. The group as a whole are committed to providing clinically led technical and operational excellence for the doctors who request their pathology services, their patients, and their own staff.

University College London Hospitals NHS Foundation Trust

UCLH (University College London Hospitals NHS Foundation Trust), situated in the West End of London, is one of the largest NHS trusts in the United Kingdom and provides first-class acute and specialist services. The state-of-the-art University College Hospital which opened in 2005 is the focal point of UCLH alongside five cutting-edge specialist hospitals. UCLH is committed to research and development and forms part of UCL Partners which in March 2009 was officially designated as one of the UK’s first academic health science centres by the Department of Health. UCLH works closely with UCL, translating research into treatments for patients.

Royal Free London

The Royal Free London began as a pioneering organisation and it continues to play a leading role in the care of patients. Their mission is to provide world class expertise and local care. Established in 1828 by William Marsden, the Royal Free’s founding principle was that they would take in anyone who needed treatment, regardless of their wealth or background, the first hospital in London to do so.

In the 21st century, the Royal Free continues to lead improvements in healthcare and is proud to have some of the best clinical outcomes in the country. Their mortality rates have been consistently among the best in English trusts for many years. It runs a number of specialist services, including for liver and kidney transplantation, plastic surgery, haemophilia, Parkinson’s disease and vascular surgery.
