Fecal calprotectin levels by the two rapid tests according to the disease status.
(A) iChroma calprotectin tests, (B) Buhlmann Quantum Blue tests.
Fig 2.
Correlation between fecal calprotectin results by iChroma calprotectin and Buhlmann Quantum Blue assays.
The correlation was stronger in patients with active IBD (r = 0.738) than in the other groups (r = 0.504).
Fig 3.
ROC curve analysis of iChroma calprotectin and Buhlmann Quantum Blue assays for detecting active IBD.
The AUCs were 0.812 and 0.826 for iChroma and Buhlmann Quantum Blue, respectively.
