IL6 and inflammatory bowel disease: (2024) validated a similar device (IBD AWARE) measuring CRP, IL-6, and FC, with expression of FC that was significantly elevated in the active cohort compared with the remission cohort in perspiration (P < 0.05; median = 906.69 ng/mL; active 95% confidence interval [CI], 466.0–1833 ng/mL; remission 95% CI, 328.4-950.8 ng/mL), serum (median = 1860.82 ng/mL; active 95% CI, 1705–2985 ng/mL; remission 95% CI, 870.2–1786 ng/mL), and stool (P <.05; median = 126.74 μg/g; active 95% CI, 77.08-347.1 μg/g; remission 95% CI, 5.038-190.4 μg/g) (22).
