<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been having severe abdominal pain and I suspect it might be appendicitis. What should I do?  <response>: To properly diagnose appendicitis, well need to run some tests. Well start with some hematologic tests and complete blood count to check your blood for signs of infection. Well also need to perform a radiographic imaging procedure, like an X-ray computed tomography scan CT scan, to get a detailed image of your abdomen. Additionally, well need to perform a urinalysis and kidney function tests to rule out other potential causes of your symptoms. And of course, if we do diagnose appendicitis, well need to provide intravenous fluid replacement.
