IBDoc® Calprotectin Home Testing

Supporting New Standards of Care for IBD
with the first CE marked Calprotectin Patient Self-Test

Managing chronic conditions such as diabetes and hypertension through patient self-testing has become common place.

It is now also possible for sufferers of inflammatory bowel disease (IBD) to manage their condition from home with the ability to perform faecal calprotectin assays themselves in the privacy of their own homes. Test results are measured using an App on their smartphones and transmitted to their clinician.



With the introduction of IBDoc®, the first CE marked Calprotectin home test, new sophisticated technology enables patients to perform quantitative calprotectin tests themselves and then use their smartphones to read the results.

More Regular Patient Monitoring

IBDoc provides a practical way for more frequent monitoring of patients in the privacy of their own home. Under the guidance of clinicians, regular monitoring allows for a customised, patient centric approach for therapy and disease management helping to predict possible relapse and assisting with therapy optimisation.

Remote Access

IBDoc enables clinicians to monitor their patients remotely and better manage clinic availability for more severe cases. It also means vulnerable patients do not need to visit hospital uneccessarily.

  • First CE marked Calprotectin Home Test

  • Excellent correlation with laboratory based tests

  • Quantitative rapid test with measurement of calprotectin in the range 30 – 1000µg/g

  • Simple sample preparation devices minimises pre-analytical errors

  • All components contained within the kit to perform a test with simple instructions

    • Pictorial IFU guide

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.

Personal Portal for Direct Management by the Clinican

The IBDoc Portal is a secure, encrypted, user friendly application for clinical professionals to manage their IBD patients.
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.

Excellent Correlation of Results

IBDoc provides consistent results that correlate with other BÜHLMANN Calprotectin assays:

  • BÜHLMANN Quantum Blue® fCAL


  • BÜHLMANN fCAL® turbo

Calprotectin Home Testing - What do the patients think?

Kezia Allen Pathology Project Specialist at Basildon University Hospital conducted a survey after IBDoc® had been in use there for 2 years, with around 250 patients who were actively using the system.

Having the result straight away, instead of weeks waiting, is so beneficial as you can start on the medication you require.

Absolutely love it!
I actually get upset when they send out a normal stool sample test and not the IBDoc.


IBDoc Test Procedure

  • 1. Prepare the Test

    To start the test procedure the patient logs into the downloaded CalApp® on their smartphone with their IBDoc® account username and password. They then collect a stool sample with the easy to use faecal collection paper sheet included in the IBDoc® Test Kit.

  • 2. Extract the Sample

    The sampling pin of the CALEX® Valve extraction device is dipped into the stool sample a few times with a twisting motion. This collects a defined amount of stool in the grooves of the CALEX® Valve pin. The pin is placed back into the tube through the upper funnel.

  • 3. Load the Test Cassette

    The CALEX® Valve tube is applied onto the test cassette and a precise amount of extract is released by turning the lever. After a few seconds, when the membrane strip of the cassette gets visibly soaked, the lever is closed.

  • 4. Read the Test Cassette

    Results are read using the smartphone camera. Placing the camera above the cassette focuses and automatically takes a picture. The image is analysed through a sophisticated image processor and a quantitative result is calculated by the CalApp®.

  • 5. Save the Test Result

    Using a traffic light code system the result is classified as NORMAL, MODERATE, or HIGH. All the results performed on one smartphone are saved locally and can be accessed at any future time.

  • 6. Doctor Is Notified

    The result taken with the CalApp® is automatically transferred to the IBDoc® Portal and the patient’s doctor is immediately notified. Depending on the test result the doctor can communicate with the patient to advise on further therapeutic steps to be taken.


Frequently Asked Questions

Is the IBDoc available over the counter?

No, it is only available through clinicians

How secure is the data?

There is a two way encrypted communication between the App and the portal with test results backed daily. No patient information is visible to anyone other than the clinic.

What will I see on completing a test?

In all instances the clinical team will receive the numerical result, but here are three options for patients to view results:

  • A red/amber/green traffic light system and the actual result (between 30 – 1000µg/g)

    • <30µg/g means that the result was below 30µg/g

    • >1000µg/g means that the result was higher than 1000µg/g

  • Just the red/amber/green categorisation

  • A blue screen with ‘Test Done’

Which option you see will depend on your clinical team – they will determine this when they set up an account for you.
