What Affects the Test
Reasons you may not be able to
have the test or why the results may not be helpful include the
following:
- You just had another test that uses barium
. An upper gastrointestinal endoscopy
should not be done less than 2 days after you have an upper gastrointestinal
(GI) series so your doctor can see your stomach and small
intestine.
- You have moderate to severe bleeding in the
gastrointestinal tract.
