In this month's "Hot Topic," Jess Peterson, M.D., discusses changes to Mayo Clinic Laboratories’ hematology FISH menu to increase awareness, provide reasoning, and highlight some of the great things that are coming.
Andrew Feldman, M.D., discusses the different tools and techniques Mayo Clinic Laboratories uses to accurately diagnose and classify T-cell lymphomas to help provide clinicians with the diagnostic answers they need to treat their patients.
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.

This week’s Research Roundup highlights high grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements with diffuse large B-cell lymphoma morphology.
