Authors: Garland E. Pendergraph, PhD, JD, MLS(ASCP)SM, HCLD/CC(ABB); Kwi Simmons, MT(AAB)
Reviewer: Judi Bennett, MT, BSM

This course includes an overview of the function of prion proteins and the differing theories as to how prions cause several different neurodegenerative diseases. The causes and symptoms of the four types of infectious and classical prion diseases will be explored, as well as the recommendations for safe handling of blood and body fluid specimens from individuals infected with prion diseases.
