Calprotectin results in 20 minutes – right on your smartphone

Calprotectin is considered an important inflammation marker in the diagnosis and monitoring of complaints in the gastrointestinal tract. In inflammatory bowel disease, fecal calprotectin concentration can be used to objectively document therapeutic success and to monitor patients without symptoms.

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. It serves as an aid in the monitoring of inflammatory bowel diseases (IBD).

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 can be shared with treating healthcare professionals (optional).

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 evaluated and released 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. Attention: Not all smartphones meet the requirements of the app. You can see a list of already supported smartphones below.

Your benefits

  • Quantitative results at home in 20 minutes
  • Storage of the test kit at room temperature (+4 to 30°C)

Hint

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.
