Kawasaki disease can be diagnosed in case a person has the following symptoms:
- Fever persists for more than five days
- Polymorphic rashes
- Enlarged lymph nodes in the neck
- Bilateral non-suppurative conjunctivitis
- Multiple changes to the mucous membranes
- Any substantial changes or redness of the throat, lips and tongue
- Skin peeling and swelling
Since there are some cardiac symptoms associated with the disease, two-dimensional echocardiography is done to check for the presence of any coronary artery disease.
Furthermore, some tests may be carried out to support diagnosis of Kawasaki Disease. The tests include:
- C-Reactive Protein (CRP) – It is the type of protein that is produced by the liver and causes inflammation. It is raised.
- Erythrocyte Sedimentation Rate (ESR) test – To check for inflammation by taking a sample of blood.
- Platelet Count – In cases of Kawasaki disease, the platelet count is considerably higher than the normal limit.
- Urine Test – This test is conducted to check if some other underlying condition is causing the symptoms.
