Isabel has saved me and a few patients a lot of woe...

- Bob Eanett, MD, Watson Clinic, Lakeland, FL, USA

I was really sceptical of Isabel at first thinking it was going to replace our brains, but having used it a number of times it’s actually a way to make our thinking better... It’s a really exciting time to see technology help us. Our brain is still the most important tool in the job... but having Isabel just makes us better diagnosticians and better physicians.

- Andrew Olson, Chief Resident, University of Minnesota Medical School

The value of Isabel is the fact that they have amassed such a large differential diagnosis that it makes you think about abnormal diagnoses much more. Physicians can’t ignore the fact that we can’t remember everything, and we have to learn how to take advantage of tools such as this.

- Neal Thomas, MD, Asst Professor of Pediatrics, Pennsylvania State University College of Medicine

Isabel ensures that I consider the broadest of differential diagnoses and prevents diagnostic tunnel vision.

ISABEL is a powerful and wonderful tool that is useful for both advanced clinicians and learners. For the experienced, it can serve as a reminder of the zebras that we sometimes overlook. For learners, it can be used as a tool to help build their differential diagnoses skills. It truly is a gift in caring for patients.
