<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing heartburn and chest pain. My friend who is a nurse thinks I might have a hiatal hernia. What tests do I need to confirm this?  <response>: Based on your symptoms, you may indeed have a hiatal hernia. To confirm this diagnosis, I would recommend a few medical tests including hematologic tests, complete blood count, glucose measurement, electrolytes panel, kidney function tests, Electrocardiogram and possible Intravenous fluid replacement if necessary.
