@twosonmom It varies on how long of a stay. After you get an appointment they will set up any tests or procedures needed. The most mine have been is a 4 day period. Most of the time for me test and procedures.. such as blood test, imaging and endoscopy plus seeing the doctor are done over two days. I go to the Mayo in Jacksonville, so it could be a little different at the one you will go to. I am always in awe of how well the clinic and hospital are run.
My visit did not include diverticulitis diagnosis, but I imagine it will be at least blood work and imaging. if you have already had imaging done they will want a cd of the test and if you had blood work done those test results too.
