Lucid Diagnostics Inc. LUCD

What this company does

We believe that our flagship product, the EsoGuard Esophageal DNA Test, performed on samples collected with the EsoCheck Esophageal Cell Collection Device, constitutes the first and only commercially available diagnostic test capable of serving as a widespread testing tool with the goal of preventing EAC deaths, through early detection of esophageal precancer in at-risk GERD patients. EsoCheck is an FDA 510(k) cleared and CE Mark certified noninvasive swallowable balloon capsule catheter device designed for in-office targeted sampling of surface esophageal cells in a less than two minute long office procedure. We believe this proprietary Collect+Protect™ technology makes EsoCheck the only noninvasive esophageal cell collection device capable of such anatomically targeted and protected sampling. EsoGuard and EsoCheck are based on patented technology licensed by Lucid from Case Western Reserve University (“CWRU”).
