Calprotectin – rapid differentiation in unclear intestinal complaints

Calprotectin is considered an important inflammation marker in the diagnosis and treatment of complaints in the gastrointestinal tract. Close monitoring helps to monitor the effectiveness of therapy and thus increases its safety.

Preventis SmarTest® Calprotectin Home is the successor of QuantOn Cal® and is also based on the unique QuantOn® Technology, an innovative combination of rapid test and app.

Test principle
The test system consists of a rapid test that detects calprotectin in stool and a smartphone app that quantitatively evaluates the result of the rapid test by scanning the test cassette. This result is linked to the answers of a clinically validated questionnaire and transmitted to the treating healthcare professional on request.

SmarTest Calprotectin app: To evaluate the test, you need the SmarTest Calprotectin app, which is available in the App Store or Google Play Store. Smartphones based on iOS are prepared for the testing by our technical support. Android based devices that are not yet qualified by Preventis can be qualified for the test individually with the help of camera test card, if your smartphone meets certain minimum criteria.

Your benefits

  • Includes clinically validated questionnaire for a better assessment of the health status
  • Independent device qualification, test erformance and evaluation
  • Medical control via data transmission optional


Note: Please note that self-tests, like all diagnostic tests, are only part of a diagnosis and cannot replace a face-to-face consultation with medical professionals. We recommend that you seek medical advice if you have any uncertainties, questions, and especially if the test result is positive.
