Answer

Noninvasive diagnostic studies include the carbon 13 urea breath test (UBT), fecal antigen test, and serologic parameters (pepsinogen I and II, H pylori antibody) as surrogate markers of H pylori gastritis and as indicators of gastritis severity. [1, 9]

Patients with new peptic ulcer disease should have a carbon 13 UBT, they should be tested for antibody titers, or they may require an investigation for stool antigens.
