Testing

Pua Hopson, D.O., discusses Mayo Clinic Labs’ new disaccharidase activity panel, which measures levels of five digestive enzymes to identify deficiencies that cause carbohydrate maldigestion and can lead to chronic conditions like celiac disease or inflammatory bowel disease. Performed on tissue sample biopsies during upper endoscopy, the activity panel is the gold standard test for detecting disaccharidase deficiencies.

Divyanshu (Div) Dubey, M.B.B.S., explains how Mayo Clinic Labs’ new Kelch-11 antibody test — the first in the world — can confirm diagnosis, guide treatment, and improve outcomes in patients affected by testicular cancer-associated paraneoplastic encephalitis.

Sanjeev Sethi, M.D., Ph.D., discusses how Mayo Clinic Laboratories’ new immunohistochemistry test for the detection of NELL-1 antigen, a biomarker for membranous nephropathy found in 10% to 15% of patients, provides diagnostic certainty and insight on disease expression.

Bobbi Pritt, M.D., discusses how Mayo Clinic Labs’ updated PCR assay for West Nile virus provides increased sensitivity to detect virus RNA in multiple sources, identifies two virus lineages, and confirms diagnosis.

Kevin Halling, M.D., Ph.D., explains how the MayoComplete Solid Tumor panel uses next-generation sequencing to assess 514 clinically significant, cancer-related genes for genetic alterations that offer insight on treatment effectivity.

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

Meera Sridharan, M.D., Ph.D., explains Mayo Clinic Labs’ testing approach for atypical hemolytic uremic syndrome (aHUS). The serological complement panel examines nine analytes to gain a thorough understanding of the complement cascade to confirm diagnosis and direct care.

In April 2021, Mayo Clinic Laboratories announced two new tests along with numerous reference value changes, obsolete tests, and algorithm changes.

Mayo Clinic Laboratories now offers a noninvasive approach for the molecular detection of H. pylori, with results that include prediction of clarithromycin resistance delivered within 24 hours.

The following list includes updates posted to mayocliniclabs.com during the month of April.

Andrew McKeon, M.B., B.Ch., M.D., discusses updates that are being made to Mayo Clinic Laboratories' autoimmune profile that will remove some antibodies from those profiles. He describes the rationale behind the updates, reviews which antibodies are involved, and explains how the changes will streamline testing and enhance test interpretation.

Christopher Klein, M.D., discusses Mayo Clinic’s updated myasthenia gravis and Lambert-Eaton syndrome testing approach. Automatic reflex to second-line testing saves time and increases sensitivity and specificity to confirm diagnosis in patients with atypical presentation.
