1, hematological examination: including blood routine, blood sugar, electrolytes, blood calcium and other aspects of the examination, can help to find the cause of the disease. Hematological examination is also used for the detection of adverse drug reactions, commonly used monitoring indicators include blood routine and liver and kidney function, etc. 2, urine examination: including urine routine and genetic metabolic disease screening, such as suspected phenylketonuria, urine iron trichloride test should be performed. 3, cerebrospinal fluid examination: mainly to exclude intracranial infections and other diseases. In addition to routine, biochemical, and bacterial culture smears, etiologic tests for mycoplasma, toxoplasma, cytomegalovirus, herpes simplex virus, and cysticercosis should be performed and cytologic tests for abnormal leukocytes should be noted. 4. Genetic testing: Although a portion of epilepsy has been found to be genetically related, especially certain specific types of epilepsy, the current stage of medical development does not allow for the routine diagnosis of epilepsy using genetic means. Genetic testing to predict the risk of epilepsy and to guide treatment through genetic findings are also being further explored.5. Other tests: For clinically suspected causes, other specific tests can be performed according to clinical needs or realistic conditions, for example, toxic screening can be performed in cases where poisoning is suspected to cause seizures, and in cases where metabolic disorders are suspected to exist. Perform relevant tests, etc. Lumbar cerebrospinal fluid examination and genetic testing are not routine tests for epilepsy.
