Introducing IBDoc® Calprotectin Home Test

Alpha Laboratories has expanded the offering of Calprotectin tests with the launch of the BÜHLMANN IBDoc® which is the first CE marked Calprotectin home test. Utilising sophisticated technology contained within smartphones, the IBDoc enables patients to perform quantitative calprotectin tests at home.

Under the guidance of clinicians, regular monitoring is now possible for IBD patients in the comfort of their own home. This approach allows for a customised, patient centric method for therapy and disease management helping to predict possible relapse and assisting with therapy optimisation.

Easy Sample Extraction and Dispensing

The CALEX® Valve allows patients to process their own samples without the need for vortex mixing, centrifuging or pipetting. The valve at the base of the device dispenses a precise amount of liquid onto the lateral flow test device. After 12 minutes the calprotectin assay result is read using the smartphone and the data is transmitted to the clinician via a secure web portal.

Each patient test profile can be tailored by the clinician:

  • Threshold values for the traffic light system
  • Choose for the patient to see the traffic light interpretation, the actual calprotectin value or hide the results completely
  • Set the frequency of the tests for the patient.
