To help you through this difficult time, we have compiled some useful information below about Calprotectin testing, and how to use the IBDoc, which we hope will assist you when access to your IBD clinic is more tricky.

IBDoc® Helpful Hints and Tips

Before taking the test:

  1. It is recommended to take the first sample of the day as this is likely to contain the highest level of calprotectin. Urgency can be an issue in the morning, so it might help to prepare the bathroom the night before for collecting that initial sample.
  2. You don’t have to use the collection papers in the kit if you don’t find these work for you – just so long as the container is clean and the sample doesn’t come into contact with the toilet water (the bleaches and disinfectants will impact the test).
  3. It is best to take the sample in the morning and then continue with your day. In the evening when you will usually not be so rushed, the stool sample should have dissolved into the buffer and you can continue with the rest of the test.

Before loading the solution onto the cassette:

  1. Make sure the phone is fully charged.
  2. Put the phone into airplane mode or do not disturb so that no calls or texts come in whilst you are waiting for the timer.
  3. Log into the App BEFORE you apply the solution to the test cassette. If you have forgotten your password it may take longer to get password reset than the 12 minutes you have to incubate the test in which case it is ruined.
  4. Log into the App to see if the camera check needs to be completed first.
  5. Make sure the kit is ready, the cassette is open, and the card is with the blue side facing up.

Completing the test:

  1. It can sometimes take a while for the solution to flow into the cassette, don’t panic! Don’t press hard down onto the cassette, and don’t shake the CALEX when you’ve moved the leaver into position 2.
  2. The alarm might be significantly quieter than you might expect – Please make sure you listen out for it, especially the first time.
  3. If you struggle to hold the phone still for it to focus rest your elbows on the counter surface.
  4. When you have completed the test, keep the camera test card somewhere safe. The camera check is valid for a month and then needs to be redone – even if you just want to review the results, the App won’t let you until the camera test is confirmed.

How to Take a Sample for Faecal Calprotectin Testing

Calprotectin enters the stool whilst it is contact with the gut wall, and the concentration will vary depending on the transit time of the gut contents. If things are moving rapidly then it may not collect much calprotectin! For this reason it is recommended that the first stool of the day is used – this is likely to have been in the gut overnight and so should contain the highest level of calprotectin. If the first stool isn’t possible then use a sample where there has been a reasonable time between bowel movements.

Empty the bladder before collecting the sample to avoid contamination and dilution with urine. The sample must not come into contact with the toilet water which may contain chemicals that could influence the test result.

Read the Patient Blog: IBDoc® and Me

Having struggled with his disease for the last 25 years, Lee Stanley hoped that being able to use the IBDoc would help him to self manage the condition whilst expanding his extremely limited diet. After all, there is only so much chicken, carrot and rice that one person can take!

However, at the time there were no clinics offering IBDoc that Lee could access. Now that Lee has gained access to the IBDoc, he is doing a blog to chart his experience.

Join Lee on his journey and see how he gets on performing his own calprotectin tests.
