Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, if he will make an assessment of the adequacy of the NHS’s capacity for fresh freezing of (a) tumour and (b) other tissue samples.

Fresh-freezing, also referred to as snap-freezing, is a standard technique used by pathology networks to preserve tissue architecture without chemical fixatives, allowing for subsequent molecular or histological analysis, typically supporting research or advanced diagnostic applications.

Pathology services in England are delivered through 27 regional pathology networks, and offer a comprehensive range of tests, including the analysis of brain tissues.

Individual pathology services maintain their own standard operating procedures (SOPs) for fresh tissue samples and for the snap-freezing of tissue samples. These SOPs outline local capabilities and practices.

It is important that everyone, regardless of where they live, can access the latest innovations in the health and care system through research. The Department invests over £1.6 billion each year in research through the National Institute of Health and Care Research (NIHR). The NIHR’s investments for capital equipment, technology, and modular buildings support NHS trusts across England to deliver high-quality research to improve the health of the population. This investment includes cutting edge research equipment and fixed assets such as ultra-low and cryogenic freezers, to strengthen research capacity and improve access to samples for research.

The Department is exploring options to expand brain tissue freezing capacity.
