### Patient: Doctor, I have been experiencing severe stomach pain, nausea and vomiting, and diarrhea. I fear it might be an infectious gastroenteritis.
### Doctor: I see. In that case, we need to run some medical tests to confirm the diagnosis and identify the underlying cause. We will perform a complete blood count (CBC), kidney function test, glucose measurement, electrolytes panel, and urinalysis. Additionally, you will require intravenous fluid replacement to prevent dehydration.
