IBDoc® is the first self testing application for fecal calprotectin in IBD patients. Based on BÜHLMANN’s long lasting experience with calprotectin assays, IBDoc® provides IBD patients a convenient method for self testing. CALEX® Valve has been developed for simple and easy-to-handle stool extraction with a valve designed to allow the precise application of 60 µl onto the test cassette. The CalApp® smartphone application (available for iOS and Android) is used to transform smartphones into a test cassette reader using sophisticated image processing.

The product can be purchased in Canada (not in the US) and requires the creation of a clinical account in charge of monitoring their patients. This is part of our concept to ensure professional monitoring of results and a clinical follow-up if results are positive. The clinic/doctor is responsible in purchasing the IBDoc® Kits that are then distributed to the individual patients.

IBDoc has quickly become an invaluable tool for close follow-up in my patients with Ulcerative Colitis. My patients have been much happier with the quick results and the convenience of performing these tests at home compared to taking the samples to the lab. I have appreciated the benefit of being able to make changes to their management based on both symptoms and the objective measure of fecal calprotectin without the two-week turnaround I was accustomed to. The process alerts me to new results and the portal stores previous results so I can easily track my patients’ progress.

I have had the opportunity to use IBDoc within a community GI practice. It is a promising clinical test to obtain fecal calprotectin results with no delays or turnover. You are notified that the results are posted within the portal, that displays not only the results but a trending graph. Patients have expressed that it is easy to use, convenient and gives them a sense of participation in managing their disease. They are given the kit in clinic, which eliminates a trip to the lab to pick up sample containers and the trip back to the lab to drop off samples for testing. In clinic,I explain how to use IBDoc kit at home and how their results will be interpreted. I feel that fecal calprotectin results are part of the patients overall clinical assessment to help guide decision making in regards to disease activity and treatment.
