Comparison of Fecal Calprotectin Methods for Predicting Relapse of Pediatric Inflammatory Bowel Disease

Figure 2

Receiver operating characteristic (ROC) curve of fecal calprotectin (FCal). ROC of FCal comparing Bühlmann Calprotectin ELISA, PhiCal Calprotectin-EIA, and Phadia 250 EliA-Calprotectin with colonoscopy in 40 pediatric fecal samples. The solid line indicates values that have no discrimination. The performance of a test that exhibits the highest sensitivity and specificity shows an optimum cut-off value to evaluate the relapse of IBD.
