Revelatory evaluations to advance awareness and individualize care
For more than 50 years, Mayo Clinic Laboratories has been providing meaningful results to individuals seeking genetic answers. Rare genetic disorders can be among the most difficult conditions to diagnose. To provide meaningful answers, our genetic testing is developed and supported by an integrated team of clinical, genetic, and laboratory experts and uses precision technologies to reveal variations related to diagnosis and treatment. Built around a tradition of placing patients’ needs first, our testing generates personalized insights to elevate understanding of a patient’s condition.
“We understand supplemental assays come with additional cost and effort, but our commitment to providing complete and accurate results for our patients motivates us to go beyond standard lab testing processes.”
Wei Shen, Ph.D., associate director of the Clinical Genome Sequencing Laboratory at Mayo Clinic.

Cherisse Marcou, Ph.D., and Kristen Rasmussen, M.S., CGC, explain how Mayo Clinic Laboratories' WESPR whole exome sequencing reflex test provides cost-effective diagnosis of complex genetic conditions. Using samples and data from previous targeted gene panels, WESPR's wider net can identify undetected genetic variants.
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.

PACE/State of FL - The critical role of pharmacogenomics and therapeutic drug monitoring (TDM) in managing immunosuppressive therapy for solid organ transplant recipients.
For many, the path to a correct diagnosis can be long and filled with uncertainty. This story highlights the resilience and determination of one patient who navigated a complex medical journey to find answers and hope at Mayo Clinic. The patient asked to remain anonymous for personal privacy reasons.

Jessica Wright, Pharm.D., BCACP, explains how Mayo Clinic Laboratories' 3A5Q test helps determine initial tacrolimus doses for individuals after non-liver organ transplants. Optimal tacrolimus levels are one of the important factors in survival of the transplanted organ.
Justin Fugelsang and Zach Pedowitz have never met. Yet both young men were diagnosed with a rare form of Charcot-Marie-Tooth disease, called sorbitol dehydrogenase (SORD) deficiency, and both found clarity through Mayo Clinic Laboratories' innovative SORD testing. Their journeys inspire resilience, as Justin has channeled his emotions into guitar playing, and Zach has embraced educational leadership.
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 genetic counselors Carrie Lahner, M.S., CGC, and April Studinski Jones, M.S., CGC, to discuss how family medical history can inform genetic testing strategies.
