Introducing our EFT expert panel.

This panel of experts is comprised of many of the world leaders in the field of esophageal disease, specializing in the review and analysis of esophageal functional technologies and testing. MDLGI contracted with them to provide the highest level of excellence and accuracy in the analysis of esophageal diagnostic data.

A panel member analyzes all studies pertaining to high resolution esophageal manometry, ambulatory pH, and pH-impedance testing that are submitted via MDLGI. These physicians are regarded as the pre-eminent clinical authorities on esophageal testing and disorders. Many are active in helping develop current technologies in HRM and esophageal pH testing. These physicians are individually affiliated with many of the most distinguished medical facilities in the world today.

And their expertise is available to you — and your patients — exclusively through MDLGI.
