Quantitative self-testing of calprotectin for IBD monitoring at home

Preventis SmarTest Calprotectin Home test is a quantitative home test system for the determination of calprotectin in stool samples. This in vitro diagnostic device (IVD) is intended for self-testing and individual monitoring of disease activity and treatment efficacy for patients with chronic inflammatory bowel disease (IBD). SmarTest Calprotectin consists of a rapid lateral flow test that detects human calprotectin via gold-conjugated anti-calprotectin antibodies, and a smartphone app that analyses the result quantitatively based on the intensity of the control and test lines. Results are automatically sent to the patient’s doctor and logged in the Doctor’s Online Portal for their IBD team to remotely monitor.

In addition to measuring the concentration of calprotectin in a stool sample, the app also includes a clinically validated disease activity questionnaire for Monitoring IBD at Home (MIAH), enabling patients and IBD teams to view a fuller picture of Crohn’s disease or ulcerative colitis. The MIAH questionnaire results are reported as a disease activity score that correlates with endoscopically-determined disease activity, enabling swift therapeutic intervention and patient initiated follow up (PIFU).

How SmarTest Calprotectin Home works​

1. Access the online portal and set up a Competence Centre

IBD teams can set up their own Competence Centre within the portal free of charge, which forms the central point for user and patient management, data collection and viewing results.

2. Register patients

Patients are enrolled in the Competence Centre at which point an invitation letter containing a patient-specific QR code is automatically generated. Patients connect their SmarTest Calprotectin app to their IBD team’s Competence Centre by scanning their QR code using the SmarTest Calprotectin app.

3. Monitor your patients

Once a patient is enrolled in the SmarTest Calprotectin programme, every result they generate from the SmarTest Calprotectin test will automatically be dispatched from their smartphone to the Competence Centre where the results are logged for monitoring.
