A new shared pathology network is being created between East and North Hertfordshire NHS Trust, Princess Alexandra Hospital NHS Trust, West Hertfordshire Teaching Hospitals NHS Trust and Hertfordshire and West Essex Integrated Care Board (ICB).
Pathology services from the three hospital trusts transferred to a new provider on 1 March 2025. Health Services Laboratories (HSL) is contracted to deliver the new networked pathology service across Hertfordshire and West Essex ICS. This includes provision for the pathology services used by the hospital trusts, primary care and other providers in the wider community.
Key points about the new service for primary care
You won’t see too much change in the way you currently receive the pathology services:
- your test turnaround time will remain the same
- specimen collections from your practices will continue as scheduled, but they will be collected by TDL Collect – please see the information sheets on this for your place area below
- you will continue to use the online systems to order and view test results
- you will continue to receive tubes/ vials and other test stock, however how you order these consumables is different. Please use the HSL instruction sheets for your place area below to order these.

Future changes to the pathology service network
From this spring HSL will start to implement a new working model for the ICS wide pathology service network under ICB governance along with the partner hospital trusts.
A new central laboratory opening in 2026 at Croxley Park, Watford, will deliver most of the routine pathology testing including pathology services for GPs and community providers.
The existing laboratories on each hospital site will be transformed to deliver essential on-site pathology services for inpatients and the emergency department.
Throughout these developments clinical involvement will be maintained from both acute sites and GP practices to provide clinical oversight on delivering pathology services. They also maintain input throughout the 15 year contract with HSL.
Why a new provider and networked service
A single shared pathology network across the ICS will provide sustainable service for our hospitals, community services, GPs and the patients we all care for. It is part of the partnership’s collective commitment to further improve services across the region whilst also delivering a national programme initiated by NHS Improvement as directed by the by the Carter review.
The network partnership explored different options to develop a single shared pathology service. Together the partners agreed that transferring existing pathology services from within the three acute trusts to an external contractor would provide the best outcome in joining up services. The benefits included significant financial investment in state-of-the-art equipment in newly refurbished laboratories at the hospital sites, a new hub laboratory and staffing resilience – all important elements in providing a flexible and sustainable ICS-wide pathology service.
Following ICB approval of a full business case for the contract in December 2022 and a rigorous procurement process, in March 2024 the three acute trusts and the ICB entered a 15-year contract with HSL as the selected service provider. Pathology services transferred to HSL in March 2025.
