CRP and Thrombocytosis: Some laboratory data, such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), albumin and N-terminal pro-B-type natriuretic peptide (NT-proBNP) level, thrombocytosis, leukocytosis, raised transaminases, hyponatremia, and pyuria, may be helpful in the diagnosis of KD (Cho et al., 2011; Lin et al., 2015; Reddy et al., 2016; Dionne et al., 2017), but all of them are yet to find the same change in other immune and infectious disease, and cannot act as special diagnostic indexes for KD.
