In this episode of “Answers From the Lab,” host Bobbi Pritt, M.D., chair of the Division of Clinical Microbiology at Mayo Clinic, is joined by William Morice II, M.D., Ph.D., president and CEO of Mayo Clinic Laboratories, to discuss updates on the Protecting Access to Medicare Act (PAMA) and other policy changes affecting clinical diagnostics. Later, Dr. Pritt welcomes Ann Moyer, M.D., Ph.D., a molecular genetic pathologist at Mayo Clinic and chair of the hereditary genetics practice, to explore how precision therapeutics are improving cancer treatments.

Mayo Clinic Laboratories’ newly expanded Hereditary Pancreatitis Gene Panel is transforming how clinicians diagnose and manage a complex, often elusive disease. Developed through close collaboration between lab scientists, genetic counselors, and clinicians, the test uses a whole exome sequencing backbone to analyze nine carefully selected genes with strong clinical relevance. This focused approach avoids ambiguous results while empowering early diagnosis, cancer risk assessment, and family testing. Built on a whole exome backbone with reflex capabilities, the panel represents a major step forward in precision medicine — offering clarity for patients and providers, and a platform for future genomic innovation.
