Tests and diagnosis
By Mayo Clinic staffRoseola can be difficult to diagnose because initial signs and symptoms are similar to those of other common childhood illnesses. If your child has a fever and it's clear that no cold, ear infection, strep throat or other common condition is present, your doctor may wait to see if the characteristic rash of roseola appears. Your doctor may tell you to look for the rash while you treat your child's fever at home.
Doctors confirm a diagnosis of roseola by the telltale rash or, in some cases, by a blood test to check for antibodies to roseola.
