Maria Alice Willrich, Ph.D., explains kappa free light chain testing — Mayo Clinic Laboratories' data-driven approach to diagnose multiple sclerosis. The automated assay is more sensitive, cost-effective, and faster than traditional oligoclonal banding, enabling definitive answers for the challenging diagnosis.

Mayo Clinic researchers have developed and validated a new antibody test to diagnose multiple sclerosis (MS). The new test is an automated and cost-effective method compared to other tests used to diagnose MS, according to the research published in Mayo Clinic Proceedings. The test is now available through Mayo Clinic Laboratories.

John Lieske, M.D., discusses Mayo Clinic Laboratories' urinary ammonium testing. A test that takes the guesswork out of determining acid base disorders by giving nephrologists a true understanding of a patient’s true urinary ammonium level.

In February 2022, Mayo Clinic Laboratories announced fourteen new tests along with numerous reference value changes, obsolete tests, and algorithm changes.

Audrey Schuetz, M.D., provides a detailed overview of Mayo Clinic Laboratories’ new culture-based extended spectrum beta lactamase (ESBL) testing. Used to screen for the presence of multi-drug resistant gram-negative bacteria in donor stool intended for fecal microbiota transplantation, the screening test is performed on stool or swab samples taken from around the anus to detect potentially harmful ESBL bacteria that could jeopardize the outcomes of fecal microbiota transplants -- especially in patients who carry the bacteria in their gut without getting sick.

Andrew McKeon, M.B., B.Ch., M.D., explains how Mayo Clinic Laboratories' stiff-person assay provides comprehensive evaluation for individuals on the spectrum of stiff-person syndrome. In addition to guiding treatment decisions, the assay can help confirm the most-severe stiff-person phenotype — known as PERM — which is associated with potential cancers.

In January 2022, Mayo Clinic Laboratories announced twenty five new tests along with numerous reference value changes, obsolete tests, and algorithm changes.

Joseph Yao, M.D., explains how Mayo Clinic Laboratories’ SARS four-target test for viral respiratory disease can enhance patient care. The test detects RNA from SARS-CoV-2, influenza A, influenza B and respiratory syncytial virus, or RSV. RSV — which poses significant risks for infants and patients with underlying health conditions — can be treated if diagnosed early.
