Flu season is just now unfolding. But this time, it’s piggy-backed with a pandemic, which threatens to spike with the colder weather as people huddle indoors. Adding to this conundrum is the unsettling fact that, for both COVID-19 and the flu, the symptoms overlap.

William Sukov, M.D., provides an overview of the MDM2 gene amplification assay — a test that looks for amplification of the MDM2 gene region on chromosome 12q. He reviews when this test should be ordered, how it compares to other test options, and how its results can affect patient care.

In September 2020, Mayo Clinic Laboratories announced one new test along with numerous reference value changes, obsolete tests, and algorithm changes.

In August 2020, Mayo Clinic Laboratories announced five new tests along with numerous reference value changes, obsolete tests, and algorithm changes.

The results are part of a comprehensive study of 16,175 cases performed at Mayo Clinic over an 11-year period.

Divyanshu (Div), Dubey, M.B.B.S, gives an overview of the new Autoimmune Gastrointestinal Dysmotility Evaluation available through Mayo Clinic Laboratories. He discusses when this testing should be ordered, how this testing compares to previous testing approaches, and what clinical action can be taken due to the results of this testing.

One of the biggest misunderstandings about genetic testing is a perception that once a variant is identified and analyzed thoroughly, using all the best tools available, it can be associated with a specific disease or condition. But many mutations are deemed “variants of unknown significance,” meaning there is no reported (or insufficient) evidence as to whether or not they cause disease.

Horatiu Olteanu, M.D., Ph.D., gives an overview of the new T-cell receptor (TCR) β-chain constant region (TRBC1) flow cytometry marker, which is now included in Mayo Clinic Laboratories' routine diagnostic T-cell flow cytometry panel. He discusses when this testing should be ordered, how the addition of TCRBC1 compares to previous testing approaches, and how this marker can assist ordering physicians.

In the last decade or so, genetic testing has evolved from single-gene Sanger based assays to much more complex next-generation sequencing (NGS) based assays. This incredible technology has facilitated the rapid and high-throughput evaluation of many genes (hundreds of thousands of DNA strands) all at once.

In June 2020, Mayo Clinic Laboratories announced three new tests along with numerous reference value changes, obsolete tests, and algorithm changes.
