Testing

Cherisse Marcou, Ph.D., and Marissa Ellingson, M.S., CGC, discuss whole exome sequencing (WES) at Mayo Clinic Laboratories. The comprehensive evaluation uses next-generation sequencing to detect for single nucleotide variants, small insertions or deletions, and copy number variants on approximately 20,000 genes, enabling precision answers to accurately diagnose, manage, and treat patients with identified inherited illness.

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

This list includes updates posted to mayocliniclabs.com during the month of May.

Alicia Algeciras, Ph.D., describes Mayo Clinic Laboratories’ new blood test to detect NFLC, or neurofilament light chain protein. NFLC is a biomarker for several neurodegenerative conditions. The new assay can determine if a patient’s cognitive decline is due to a neurodegenerative condition or some other, reversible condition — while avoiding the need for more-invasive testing of cerebrospinal fluid.

Paul Jannetto, Ph.D., and Loralie Langman, Ph.D., discuss Mayo Clinic Laboratories' unique approach to urine drug testing for addiction rehabilitation. Designed to guide and monitor therapy, the comprehensive profile tests for the most commonly used substances, including alcohol and nicotine, for a complete picture of a patient’s substance use.

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

In this test specific episode of the  "Answers From the Lab" podcast, Melissa Snyder, Ph.D., explains how IBDP2, when used after first-line testing has failed, can distinguish between ulcerative colitis and Crohn’s disease.

Paul Jannetto, Ph.D., describes Mayo Clinic Laboratories' synovial fluid testing for patients with symptoms of failed hip arthroplasty. The Food and Drug Administration recommends testing for elevated chromium and cobalt, which can indicate a malfunctioning metal hip implant. A Mayo Clinic study found that synovial fluid testing for those elements is more sensitive than serum or whole blood testing.

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

Ann Moyer, M.D., Ph.D., discusses TPNUQ, Mayo Clinic Laboratories' genotyping test for identifying patients at risk for thiopurine toxicity. Used prior to therapy initiation, our assay evaluates for nuances in both TPMT and NUDT15, which have associations to thiopurine metabolization.

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.
