Agreement Between Home-Based Measurement of Stool Calprotectin and ELISA Results for Monitoring Inflammatory Bowel Disease Activity

Measurements of fecal levels of calprotectin made with home-based lateral flow method were in agreement with measurements made by Quantum Blue and ELISA, as long as concentrations were <500 μg/g. For patients with concentrations of fecal calprotectin above this level, findings from IBDoc should be confirmed by another method. (Netherlands Trial Registration Number: NTR5133).
