“What I Do” Bryan Betz PhD Clinical Assistant Professor Technical Director Molecular Diagnostics Laboratory
Molecular Diagnostics / Molecular Pathology Application of molecular biology techniques and knowledge to clinical laboratory diagnosis • Infectious disease • Inherited disease • Hematopathology • Solid Tumors • Identity Testing • Forensics • Pharmacogenomics Is and will continue to revolutionize the way in which diseases are diagnosed and therapeutics are employed
Molecular Pathology A Universal Discipline of Laboratory Medicine INFECTIOUS DISEASE FORENSICS HEMATO PATHOLOGY Molecular Pathology IDENTITY TESTING SOLID TUMORS GENETIC DISEASE
Molecular Diagnostics is a Rapidly Expanding Field • Molecular diagnostics is the fastest growing segment of the diagnostics industry • ~$34 billion world-wide market • 6-8% annual growth • New discoveries and technology platforms are leading to the development of more and increasingly sophisticated tests • DNA sequencing • Expression microarrays • Array CGH • Detection technology/test platforms • Majority of the innovation and discovery takes place in Universities
UM Molecular Diagnostics Test Volume and TATJan 2002 – Dec 2009
Applications of Molecular Diagnostics in Clinical Laboratory Medicine • Infectious Disease • Qualitative and quantitative detection • Microbial identification • Drug resistance • Identity Testing • Determining familial relationships • Bone marrow engraftment analysis • GVHD monitoring • Laboratory specimen identification • Forensics • Genetics (inherited disease) • Diagnosis of: • Single gene disorders • Complex polygenic disorders • Chromosomal disorders • Oncology – Solid Tumor and Hematologic • Diagnosis • Prognosis • Predict response to therapy • Monitor residual disease • Pharmacogenomics • Drug metabolism • Determine drug dosage
