In the scenario of a patient with a known seizure disorder who presents unconscious after a seizure, the initial diagnostic step that is most important is to perform basic laboratory tests. This step is crucial because it helps identify any underlying metabolic or systemic abnormalities that may have contributed to the patient's altered level of consciousness.

Conditions such as hypoglycemia, electrolyte imbalances, or infections can all lead to seizure activity or postictal states, and these can be rapidly assessed through routine blood tests. Testing for glucose levels, electrolytes, and renal function can provide immediate insights that might influence management and treatment.

While other diagnostic tools such as an electroencephalogram (EEG) are important for assessing seizure activity and monitoring brain function over a longer term, they do not address any acute metabolic issues. Brain MRI and cerebrospinal fluid analysis are also important diagnostic tools in specific contexts, but they are not typically the first step in the immediate evaluation of a postictal patient in an emergency setting. Basic laboratory tests lay the groundwork for further evaluation and are essential for determining the overall clinical picture.
