### Patient: Doctor, I have been experiencing a burning sensation in my chest and difficulty swallowing, and I think I might have esophagitis. What medical tests do I need to take?
### Doctor: I recommend that we start with a hematologic tests or a complete blood count (CBC) to check for any signs of infection or inflammation. We will also need to do a plain x-ray to see if there is any damage to your esophagus. Additionally, an electrocardiogram and electrolytes panel will be needed to check the health of your heart and the balance of your body's fluids. In case of dehydration, we may need to replace fluids intravenously. Finally, we will measure your blood glucose levels to check for any issues related to diabetes, which is a common risk factor for esophagitis.
