All

Inclusion criteria

Inclusion criteria: 1. Are aged at least 18 years (part 1, 2) 2. Are referred to their gastroenterologist for any endoscopic examination (part 1) 3. Visit their GP because of on-going unspecific gastrointestinal symptoms (abdominal pain, bloating, stool irregularities, diarrhea) for at least two weeks (part 2) 4. Underwent no earlier diagnostic procedures (endoscopy) for the current episode (part 2)

Design outcomes

Primary

MeasureTime frame
Part 1: 1.1. Sensitivity and specificity of CalproQuest for a positive Calprotectin test result 50 µg/g feces 1.2. Sensitivity and specificity of CalproQuest for a positive Calprotectin test result 50 µg/g feces and positive IBD-diagnosis. Part 2: 2.1 Feasibility of CalproQuest in daily primary care practice Timepoints: Part 1: Sensitivity and specificity (primary outcomes) will be measured 12 months after recruiting the last study centre (part 1: IBD-centre, part 2: GP) or earlier, when the target number of patients (part 1: 162, part 2: 80) has been achieved. Part 2: Feasibility of CalproQuest in daily primary care practice will be measured after the announcement of the Calprotectin test result, not exceeding 2 weeks after the consultation at the gastroenterologist or GP.

Secondary

MeasureTime frame
Part 1: Patient-reported diagnostic delay. Part 2: Patient acceptance of stool sampling. Timepoints: Part 1: Patient-reported diagnostic delay after the endoscopy exam, the whole procedure between first consultation and endoscopy will take at most 2 months. Part 2: Patient acceptance of stool sampling directly after fecal samples will be obtained at home (not exceeding 2 weeks after the consultation at the gastroenterologist or GP).
