ADA and Hyponatremia: Although KD diagnosis is clinical, laboratory findings (elevated erythrocyte sedimentation rate and C‐reactive protein level, hyponatremia, hypoalbuminemia and elevated liver enzyme levels) may be helpful in evaluating suspected cases and differentiating KD from other conditions.19 We analyzed a number of laboratory parameters and found that D‐dimer, PCT, BNP, TP, CK‐MB, ADA, ALT, TC, Tbil, Dbil, Ibil, TBA, UA, pre‐albumin, WBC, neutrophil count, platelet count, PDW and CRP differed significantly between acute KD and convalescent KD.
