This study aimed to validate the FC’s diagnostic and mucosal healing assessment value of FC and a noninvasive composite index in pediatric CD.Patients and Methods: Patients aged 2– 17 years who underwent ileocolonoscopy for suspected or established CD were enrolled. Based on endoscopy, participants were classified into three groups: controls (functional gastrointestinal disorders), MH (mucosal healing, SES-CD < 3, indicating minimal or absent visible inflammation), and ML (mucosal lesions, SES-CD ≥ 3). Fecal and blood samples were collected before endoscopy. Group differences were assessed using Kruskal–Wallis/Dunn’s tests; correlations were evaluated via Spearman coefficients; ROC analysis was used to assess diagnostic performance. A composite index was constructed by weighting CRP, ESR, and IL-6 based on their correlations with FC.Results: Among 123 participants, FC levels significantly differed across groups (P
