However, laboratory and echocardiographic findings, such as elevated erythrocyte sedimentation rate and C-reactive protein levels, hyponatraemia, hypoalbuminaemia, and the presence of coronary aneurysms, can aid in evaluating suspected cases and distinguishing KD from other conditions.5 In certain instances, patients may not meet the classic criteria for KD and are thus classified as having IKD disease so clinical diagnosis and treatment are easily delayed. The gene discussed is CRP; the disease is coronary aneurysm.
