Kawasaki Disease

Diagnosis

Mayo Clinic doctors with training in treating children with medical conditions (pediatricians), infectious disease specialists, doctors with training in treating children with heart disease (pediatric cardiologists) and other specialists work together to diagnose Kawasaki disease.

Mayo Clinic doctors have experience in diagnosing Kawasaki disease and ruling out conditions with similar symptoms. Some children develop coronary artery changes without having all of the signs of the condition, and they may have conditions called atypical Kawasaki disease or incomplete Kawasaki disease.

To diagnose Kawasaki disease, your child's doctor will evaluate your child for several specific signs and symptoms. Your child's doctor will perform a thorough physical examination and also may perform several tests.

• Blood tests. These tests may help rule out other conditions and check your child's white blood count.
• Echocardiogram. In this test, sound waves produce detailed images of your child's heart. This test assesses the structure of your child's heart and how your child's heart and arteries are functioning.
• Electrocardiogram. In this test, sensor patches with wires attached (electrodes) measure the electrical impulses given off by your child's heart.
• Urine tests. These tests may be done to help rule out other conditions.
