Explain why you agree or disagree with the diagnosis of ileitis as the reason for the test being requested

I have searched for more details about the question:

You are working in a large multi-specialty practice where you and one other person share the responsibility of scheduling necessary diagnostic tests and surgical procedures for the patients. You are preparing to send diagnostic test requests to the hospital lab and you notice that your coworker has written the diagnosis of ileitis on a request for a 24-hour esophageal pH monitoring test.

I disagree with doing a 24-hour esophageal pH monitoring test. In a patient with ileitis, the esophageal pH is unrelated with the condition. Unless the patient as a concurrent disease such as chronic GERD but it should be indicated also in the diagnosis. A more fitting diagnostic test for ileitis would be blood exams such as CBC and platelet count, urinalysis (as UTI can present with signs and symptoms similar to ileitis), and a colonoscopy to directly visualize the rectum, large intestine, and the terminal ileum of the small intestine. 

Ibelieve the answers are a and c.
