Routine tests needed for Tourette’s syndrome include blood tests, electroencephalogram, brain imaging and visual-auditory attention tests. 1. Blood test: routine blood test can check whether there is any infection, blood sedimentation, exclude rheumatic chorea through anti-chain O, C-reactive protein, liver function and plasma copper blue protein to exclude hepatomegaly. At present, some scholars believe that some children suffer from Tourette’s syndrome because of micronutrient deficiencies in the body, so micronutrient tests can also exclude some diseases. 2. Electroencephalography: can rule out epilepsy in children. 3. Imaging examination of the brain: it can exclude pediatric external hydrocephalus, early infantile epileptic encephalopathy, pediatric posterior cranial fossa hydrocephalus syndrome, pediatric chronic subdural hematoma, pediatric subdural hematoma, intracranial space-occupying lesions and other brain diseases. 4. Auditory-visual attention test: can assist in determining the presence of ADHD manifestations. Diagnosis of Tourette’s syndrome routinely requires the above tests, and the specific tests required should be determined by a specialized physician based on the child’s condition.
