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.

Central nervous system infections, such as meningitis and encephalitis, can be devastating for affected patients. While specific treatments are available for some of these infections, it first requires identifying the precise cause of infection. To meet that need, Mayo Clinic Laboratories has developed a metagenomics assay that can identify more than 1,000 pathogenic organisms in cerebrospinal fluid. The innovative assay, which uses an approach known as shotgun metagenomic sequencing, is one of the only such tests currently available.

Mayo Clinic Laboratories introduces the Inherited Parkinson’s Disease Gene Panel (Mayo ID: PARDP), a collaborative breakthrough poised to transform Parkinson’s disease diagnosis and treatment. Led by Rodolfo Savica, M.D., Ph.D., and Zhiyv (Neal) Niu, Ph.D., this comprehensive test offers unparalleled insights into Parkinson’s genetics, unveiling novel gene associations and enhancing diagnostic precision through next-generation sequencing. The panel’s capabilities include detecting subtle genetic variations and identifying familial patterns, promising personalized medicine advancements.

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.

Recognizing the powerful role genes can play in diagnosing illness and guiding treatment, the Division of Laboratory Genetics and Genomics at Mayo Clinic spearheaded a testing expansion, implementing and upgrading more than 60 advanced sequencing and biochemical assays in 2023 and planning for even more this year.

Endometrial cancer affects thousands annually and ranks as the fourth most common cancer among women in the United States. At the forefront of innovative discoveries in endometrial cancer diagnostics are Mayo Clinic's Department of Laboratory Medicine and Pathology consultants. Sounak Gupta, M.B.B.S., Ph.D., vice chair of Oncology Practice for the Division of Laboratory Genetics and Genomics; Maryam Shahi, M.D., senior consultant for Anatomic Pathology; and Andrea Mariani, M.D., M.S., division chair of Gynecologic Surgery, explore the critical significance of molecular profiling and collaborative efforts driving these innovations, highlighting Mayo Clinic’s revolutionary influence on patient care.

For over two decades, Mayo Clinic has been at the forefront of cardiovascular (CV) genetic testing. The current test menu features 24 different panels that span over 300 genes linked to inherited cardiovascular disorders, many of which are rare and challenging to diagnose. Whereas many labs operate in a “silo” — meaning they take a genetic specimen, test it, and then return a result with limited input — Mayo Clinic takes a much more expansive approach.

In a recent discovery by Mayo Clinic Laboratories, a novel hemoglobinopathy category was identified and termed epsilon gamma thalassemia. The first instance of the disorder was found in 2017 when an obstetric patient underwent a routine screening for blood-related illnesses such as sickle cell disease and thalassemia. Upon completion of additional tests, doctors found an abnormality they had never seen before.

Mayo Clinic’s cardiac (CV) remote monitoring service uses the compact MoMe Kardia cardiac monitoring device that yields a continuous, 24/7 stream of a patient’s ECG and motion data, no matter their location. Any troubling or burgeoning events are observed virtually the moment they occur, allowing one of Mayo Clinic’s certified rhythm analysis technicians to intervene and facilitate care in near real time. And this is only the beginning; remote patient services are the way of the future, and the future is already here.

Tying together the expertise and curiosity of Mayo Clinic autoimmune neurology researchers with eager patients who have rare disease and are looking for answers, the innovative collaboration benefits both patients affected by MOGAD and scientists on the front lines of discovery.

VEXAS syndrome is a severe autoinflammatory disease that results in a spectrum of rheumatologic and hematologic conditions. The underlying cause of newly identified VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome — somatic mutations in the UBA1 gene of blood cells — was discovered at the National Institutes of Health (NIH) in 2020. Within six months, Mayo Clinic Laboratories was able to add a UBA1 test to the MayoComplete panel, as the team simultaneously worked on a single gene assay to allow doctors to test specifically for UBA1 mutations to screen patients for VEXAS syndrome. The team opted for a droplet digital PCR test — a novel and highly accurate approach to testing for UBA1 gene mutations.
