CellTolerance uses real-time, live-cell visualisation of the intestinal mucosa via Cellvizio®. This allows you to observe cellular-level responses of the gut barrier to selected food exposures, potentially revealing food-induced mucosal responses that may underlie symptoms in patients where conventional diagnostics and elimination diets have failed.

CellTolerance® is designed around the first and only endomicroscopic diagnostic that gives cell-level insights of the intestinal barrier function, right where the food is absorbed into your body.

CellTolerance® is a science-driven program developed by Mauna Kea Technologies to address food-related gastrointestinal intolerances through cutting-edge cellular imaging and personalised dietary management. The program is built around live cell-response visualisation using the Cellvizio® confocal laser endomicroscopy platform, a mature technology with over 1,100 peer-reviewed publications and decades of real-world use across multiple specialties¹.

By combining this objective, real-time gut barrier assessment with a structured, multi-disciplinary program of dietitians and clinicians, CellTolerance® aims to offer a more precise, evidence-informed pathway for patients with suspected food-triggered GI symptoms, helping clinicians deliver personalised care and patients achieve better outcomes.
