Non-invasive methods include serological testing, fecal antigen test, and urea breath test. Several serological tests that detect serum antibodies to H. pylori are commercially available.
In addition H. pylori status was conrmed by rapid ureasi test and 13C-urea breath test. Result: A total of 5102 consecutive patients were enrolled.
Available Tests for Helicobacter pylori Infection*. Non-endoscopic Serologic test. Urea breath test (Active test).
Table 1. Summary of false negative urea breath test results induced by using standard doses of different proton pump inhibitors for 14 days.
Our study shows that omeprazole at standard dose is able to negatively affect the result of the urea breath test for the diagnosis of H. pylori infection. The rate of false-negative tests after 14 days of omeprazole therapy was 13.9%.
Prior use of a range of medications (see Table 1) can interfere with the test, either by partially suppressing H.pylori growth (rendering the test falsely negative) or by
C urea breath test be a new standard in noninvasive diagnosis of Helicobacter pylori infection?
Also known as: H pylori; H-pylori; H. pylori antibody test; H. pylori stool antigen test; H. pylori breath test; Urea breath test; CLO test; Rapid urease test (RUT) for H. pylori.
If you are pregnant, the radioactive urea breath test for H. pylori is not usually done, because the radiation could harm your child.
