Cyted Health develops and delivers molecular diagnostics for earlier detection of diseases of the esophagus. Its EndoSign capsule-sponge device collects esophageal cells without a conventional endoscopic procedure; laboratory biomarker testing and molecular analysis examine the sample for changes associated with Barrett’s esophagus, esophageal cancer and other conditions. The company combines cell collection, laboratory processing and test reporting to support clinicians’ diagnostic and surveillance decisions, with research using molecular characterization, statistical modeling and image-based machine learning to develop further tests. Its services are used in UK NHS and community settings, and it is expanding US laboratory and commercial operations. FDA 510(k) clearance applies to the EndoSign cell-collection device; it is not a blanket approval of every diagnostic assay. The Cyted Health brand covers Cyted Ltd and its UK and US subsidiaries.
