Comparison of diagnostic serum ferritin, platelet count, ESR, CRP, and NT-proBNP cut-off values between patients with KD and those with other acute febrile illnesses

Diagnostic marker Cut-off value Area under curve 95% Confidence Interval Sensitivity (%) Specificity (%) P
Ferritin (µg/L) 120.8 0.830 0.704–0.955 74.5 83.3 0.009
Platelets (× 109/L) 279.5 0.750 0.526–0.974 76.6 83.3 0.048
ESR (mm/hr) 37 0.897 0.741–1.000 93.6 83.3 0.002
CRP (mg/L) 44 0.812 0.013–0.988 78.7 83.3 0.013
NT-proBNP (ng/L) 571.3 0.848 0.711–0.984 66.0 83.3 0.006

Abbreviations: ESR, erythrocyte sedimentation rate; CRP, C-reactive protein; NT-proBNP, N-terminal pro-brain natriuretic peptide; KD, Kawasaki disease. Receiver operating characteristic (ROC) curves were used to determine a cut-off value to distinguish between patients with KD and patients with other acute febrile illnesses.
