In this issue of Clinical and Translational Gastroenterology (CTG), we are delighted to introduce a new feature: The Clinician's Toolbox: Understanding Our Tests. These articles will provide an in-depth exploration of a single diagnostic test used in gastroenterology, pancreatology, or hepatology and are meant to help busy clinicians understand the important nuances associated with the highlighted tests. Each of these reviews will include an overview of the test, its indication(s), how it is performed, the performance characteristics (sensitivity, specificity, positive and negative predictive values, and likelihood ratios), conditions that make the test results inaccurate and how to manage such results, how clinicians should incorporate the testing into clinical care or research studies, a brief discussion of any alternative tests that may replace or complement the test, and relevant billing and cost information. Every effort will be made to ensure these articles are free from commercial bias, including requirements that authors have no relevant conflicts of interest.
Our inaugural Clinician's Toolbox, “A Practical Overview of the Stool DNA Test for Colorectal Cancer Screening,” was written by Dr Sanya Anand of SUNY Downstate Health Sciences University and Dr Peter S. Liang of NYU Langone Health. Future articles already under preparation will focus on breath testing for small intestinal bacterial overgrowth and fecal elastase for the diagnosis of exocrine pancreatic insufficiency. Authors are welcome to submit manuscripts reviewing whatever tests they consider essential, although potential topics should be pre-reviewed by the Editor-in-Chief, Brian Jacobson ([email protected]). The CTG Editorial Board encourages senior authors to collaborate with mentees who are building their reputation in a particular subspecialty and to join us in embracing diversity, equity, and inclusion. We hope you enjoy this new feature and find it helpful in the care of your patients.
