Scientists continuously develop new assays to fill unmet diagnostic needs. While methods such as quantitative PCR have emerged as essential tools in molecular diagnostics, scientists developing and administering these assays still must overcome technical challenges. In this podcast series, The Scientist’s Creative Services Team talks to experts about their experiences designing and implementing assays and protocols for future molecular diagnostics.   In this episode, Deanna MacNeil from The Scientist’s Creative Services Team spoke with Ming-Sound Tsao, a senior scientist and clinician at Princess Margaret Cancer Centre, about considerations and variables for choosing appropriate assays in precision lung cancer treatment, including biomarkers, internal controls, test sensitivity, and specificity.   Welcome to Molecular Diagnostics: An Eye Toward the Future, a special edition podcast series produced by The Scientist’s Creative Services Team.
