A blood test for prion disease
A sensitive and specific blood test has been developed that could be used to limit the risk of transmission of prion disease through the blood supply (link to papers one and two).
Prion diseases, also known as spongiform encephalopathies, are uniformly fatal, chronic degenerative neurological diseases caused by misfolding of a cellular protein, PrPC. Transmissible encephalopathies may be acquired by organ transplant, receiving contaminated blood, or the ingestion of contaminated food.
