A breath test used to test for H. pylori
(Helicobacter pylori), an infection caused by bacteria in your stomach. You
will be asked to breath into a small collection bag. You will then be asked to
drink a solution before breathing into a second bag. If your test shows you
have H. pylori, you may be given a treatment of antibiotics. After taking
antibiotics, your breath test may be repeated to see if the antibiotics helped.
