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.

PACE/State of FL - The role of cytology specimens in molecular genetic testing, emphasizing their effectiveness in identifying biomarkers critical for targeted therapies in patients with cancer.
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.
John Logan Black, M.D., explains how Mayo Clinic Laboratories' UGT1A1 tests (Mayo IDs: U1A1Q and UGTFZ) identify genetic variants that increase the risk of potentially life-threatening reactions to irinotecan, a chemotherapy agent.
Dr. Dong Chen and Dr. Sounak Gupta joined the “Becker’s Healthcare Podcast” to discuss the molecular testing space and its important role in personalized cancer treatment. Dr. Chen and Dr. Gupta highlighted the importance of selecting the right molecular tests for patients, the impact of genetic testing on cancer diagnosis and treatment, and how Mayo Clinic Laboratories is helping physicians make informed decisions for the best patient outcomes.
PACE/State of FL - The latest ASCO guidelines for selection of germline genetic testing panels for cancer patients.
Matthew J. Schultz, Ph.D., and Amy L. White, M.S., CGC, explain how Mayo Clinic Laboratories' unique urine assay (Mayo ID: SORD) screens for peripheral neuropathy arising from SORD gene variants. Although recently identified, SORD-related peripheral neuropathy is fairly common.
Thanks to advocacy work by a group of medical experts, including some from Mayo Clinic, the U.S. Department of Health and Human Services now recommends all states screen for infantile Krabbe disease to help save newborn lives.
Ann Moyer, M.D., Ph.D., explains how Mayo Clinic Laboratories' unique genetic tests identify patients at high risk of severe reactions to fluoropyrimidines — a type of chemotherapy drug. Test results can guide clinical decision-making for safer cancer treatment.
