The Pritchard Laboratory focuses on oncology molecular diagnostics, particularly the source and utility of cell-free nucleic acid biomarkers in blood, and the development of innovative molecular diagnostics for the identification of DNA repair gene mutations that can guide therapeutic decision-making. His clinical work focuses on applications of next-generation sequencing gene panels for cancer risk assessment and precision treatment. He has led the development and implementation of the ColoSeq™ Lynch and Polyposis Syndrome Panel and UW-OncoPlex™ Cancer Gene Panel, both of which are in current clinical use for cancer patients and their families.
