Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, pursuant to the Answer of 19 May 2025 to Question 51941 on Paraneoplastic Encephalomyelitis: Diagnosis, how many laboratories provide blood testing for Paraneoplastic Encephalomyelitis.

There are a number of laboratories in England which provide blood testing for paraneoplastic encephalomyelitis, although the Department has not made a specific formal estimate of how many there are. Several National Health Service laboratories across the United Kingdom also offer diagnostic testing for paraneoplastic antibodies. In England, these laboratories include the University College London Queen Square Institute of Neurology, and the Oxford University Hospitals NHS Foundation Trust.

The NHS in England does not routinely send blood samples to the United States for analysis when testing for paraneoplastic encephalomyelitis. There are specialised laboratories within the UK which the NHS in England uses to conduct these tests.
