The most accurate test to find a peptic ulcer is called an upper gastrointestinal endoscopy (also known as EGD).  This test is done under sedation or anesthesia (so there is no pain or discomfort), and the doctor passes a small tube through your mouth into your esophagus, stomach and upper small intestine to look for an ulcer.  It takes about 5 minutes to do, and although complications can occur, they are quite rare when a well-qualified GI specialist is doing the procedure (complications should be no more than 1 in 1500-2000 cases).  A less invasive test, not done frequently any more, is an upper GI series X-ray, where the patient swallows barium (X-ray dye) and X-rays of the stomach are done.  It is less likely to find an ulcer than endoscopy. 
Another test that may be done before either of these is a test to look for the most common cause of ulcers, a bacteria called H. pylori.  This can be assessed through a stool sample or a breath test done at a local lab (blood testing for this is inaccurate and I do not recommend that test). If you are young and healthy, this is often the first test performed as it is not expensive and is completely noninvasive.
