Ok those sound good, although there is no test for IBS. I think you need a gastric emptying scan too.
Ok.Doctor ordered a stool sample and a series of tests to include IBD, IBS and Celiac disease. I will get it all done on April 29th.
Welcome to the gastroenterology community! I would recommend asking your doctor for a gastric emptying scan to check for gastroparesis which is slow emptying of the stomach. Good luck.
