Pregnancy tests do not detect epilepsy, whether for the pregnant woman or the fetus. To determine if the patient has epilepsy, the pregnant woman needs to visit a neurologist and provide a detailed medical history. The diagnosis of epilepsy relies on the medical history, not on laboratory tests. If the patient has a clear history of seizures, such as seizure loss of consciousness with generalized convulsions lasting 1-2 minutes, inability to recall the seizure process after the seizure, and a period of hazy and blurred state of consciousness, this history supports seizures. This is the time to refine the cranial MRI as well as the EEG, the former can help clarify whether there is an intracranial organic lesion and the latter can help clarify whether there are epileptic waves. If the EEG reveals epileptic waves such as spikes, spines or spikes and slow waves, it can further help to confirm the diagnosis. For fetuses, no test can detect the presence or absence of epilepsy in advance.
