Gastrointestinal Lymphoma Panel

Gastrointestinal Lymphoma Panel


Row of Dogs and Cats


Gastrointestinal biopsies, both surgical and endoscopic, are frequently submitted in cases of nonspecific gastrointestinal clinical signs. Most often, these samples are intended to differentiate between infectious, inflammatory, and neoplastic conditions. Differentiating gastrointestinal inflammation (inflammatory bowel disease) from lymphoma can be difficult and it has been shown that immunophenotyping can improve the accuracy of diagnosis. This is especially useful for endoscopic biopsies, and in some instances, full thickness biopsies.
