New blood tests can detect prions

Screening could prevent spread of infectious proteins through transfusions

prion blood test

PRION PROPAGATION  A technique called protein misfolding cyclic amplification can be used to test blood for infectious, disease-causing proteins called prions (an apparatus used in the process, shown). The test takes advantage of prions' ability to convert a normal brain protein into the prion form.
