How is Kawasaki Disease Diagnosed?

There is currently no single diagnostic blood test for Kawasaki Disease – in other words no single test which can tell us if a child has Kawasaki Disease.  It can be diagnosed when there is persistent fever and any two or more Kawasaki Disease symptoms are present. Not all symptoms have to be present for a diagnosis to be made.  Kawasaki Disease symptoms can appear in series – one after the other, so may not be present all at the same time.  In very young children we know that often there are very few symptoms.

All these issues mean Kawasaki Disease can be difficult to recognise – especially as some of the symptoms may have been and gone by the time Kawasaki Disease is being considered.  It is important to try to remember what has happened with your child and what symptoms there have been over previous days, when seeking medical advice.
