Clinically relevant overview of key genetic factors, testing strategies, and post-result care.

Joshua Bornhorst, Ph.D., explains how Mayo Clinic Laboratories' labile copper assay (Mayo ID: LBCS) improves upon standard blood tests for Wilson's disease. The new assay measures not just overall copper but also the fraction of copper that is bioavailable, or labile bound.

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.

Mayo Clinic Laboratories has developed a cutting-edge suite of Alzheimer's disease testing. The newest assays use blood samples, avoiding the need for lumbar punctures to obtain cerebrospinal fluid. The testing suite exemplifies Mayo Clinic Laboratories' innovative business approach. As a platform company, Mayo Clinic is creating a diagnostics ecosystem to meet a wide range of testing needs and help physicians order the right tests for their patients.

Mayo Clinic Laboratories has introduced a revolutionary diagnostic test for bile acid malabsorption, a significant contributor to chronic diarrhea. Developed by Dr. Michael Camilleri and Dr. Leslie Donato, this new bile acid malabsorption panel simplifies diagnosis and improves patient care by eliminating the need for special diets or prolonged stool collection. The test's effectiveness has been validated internationally, offering new treatment avenues for patients. Discover how this innovative test is transforming clinical practice and enhancing patient outcomes.

Maria Alice Willrich, Ph.D., and Melissa Snyder, Ph.D., explain how Mayo Clinic Laboratories' unique risankizumab panel measures levels of both that drug and its antibodies in patients' blood. The results can better guide the management of patients with inflammatory bowel disease.

This three-part microlearning series is designed for healthcare professionals interested in understanding the diagnostic algorithms for celiac disease.

Maria Alice Willrich, Ph.D., explains how Mayo Clinic Laboratories' new assay provides therapeutic drug monitoring of risankizumab, or RISA. Test results help guide care for patients with plaque psoriasis, psoriatic arthritis, and Crohn's disease.

Mayo Clinic Laboratories introduces an advancement in the management of Crohn's disease with the release of a new laboratory test that measures Risankizumab levels in patients. This test will advance the therapeutic monitoring of Crohn's disease, enabling personalized treatment approaches.

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., CEO and president of Mayo Clinic Laboratories. They discuss current events including dengue outbreaks, new colon cancer screening technology, and insurance coverage of innovative lab tests.

Linda Hasadsri, M.D., Ph.D., and Huong T. Cabral, M.S., C.G.C., explain how Mayo Clinic Laboratories' targeted test panel facilitates accurate diagnosis of hereditary pancreatitis, which heightens the risk for pancreatic cancer. Test results can guide cancer monitoring for patients and their families.

Since 1992, cases of colorectal cancer have been on a slow decline, yet 52,550 people died from it in 2023. At Mayo Clinic, a cutting-edge menu of both germline (inherited genetic alterations) and somatic (tumors due to non-inherited genetic alterations) testing are two critical tools helping to improve targeted treatments for colorectal and other common gastrointestinal cancers.

Ann Moyer, M.D., Ph.D., explains how Mayo Clinic Laboratories' test panel provides comprehensive evaluation of patients with suspected monogenic early onset inflammatory bowel disease, or IBD. Accurate diagnosis is key to guiding therapy for patients, who might be as young as 2 years of age.
