Inflammatory markers were drawn due to the concern of MIS-C or Kawasaki disease despite her appearing clinically well and were significant for a pro-BNP of 622 ng/L (5-450 ng/L), ferritin of 409 ng/mL (50-200 ng/mL), WBC of 14.23 × 106/μL (6–18 × 103/uL), platelets of 936 × 103μL (150–450 × 103/uL), erythrocyte sedimentation rate (ESR) of 8 mm/hr (0-20 mm/hr) and C-reactive protein (CRP) of 2.4 mg/L (< 5 mg/L). This evidence concerns the gene CRP and Kawasaki disease.
