  2. Helicobacter pylori - Wikipedia

    en.wikipedia.org/wiki/Helicobacter_pylori

    H. pylori serologic testing, including IgG antibodies, are not recommended as a test of eradication as they may remain elevated for years after successful treatment of infection. [135] An endoscopic biopsy is an invasive means to test for H. pylori infection. Low-level infections can be missed by biopsy, so multiple samples are recommended.

  3. Rapid urease test - Wikipedia

    en.wikipedia.org/wiki/Rapid_urease_test

    Rapid urease test, also known as the CLO test (Campylobacter-like organism test), is a rapid diagnostic test for diagnosis of Helicobacter pylori. [1] The basis of the test is the ability of H. pylori to secrete the urease enzyme, which catalyzes the conversion of urea to ammonia and carbon dioxide .

  4. Urea breath test - Wikipedia

    en.wikipedia.org/wiki/Urea_breath_test

    The urea breath test is a rapid diagnostic procedure used to identify infections by Helicobacter pylori, a spiral bacterium implicated in gastritis, gastric ulcer, and peptic ulcer disease. It is based upon the ability of H. pylori to convert urea to ammonia and carbon dioxide.

    The CLO test is used to diagnose H. Pylori in patient biopsies. A sample of the biopsy is places in a medium containing urea, which H. Pylori can use in some of its biochemical pathways. Consumption of urea indicates a positive test result. [23]

  6. Peptic ulcer disease - Wikipedia

    en.wikipedia.org/wiki/Peptic_ulcer_disease

    H. pylori can be diagnosed by testing the blood for antibodies, a urea breath test, testing the stool for signs of the bacteria, or a biopsy of the stomach. [1] Other conditions that produce similar symptoms include stomach cancer, coronary heart disease, and inflammation of the stomach lining or gallbladder inflammation. [1]

  7. Gastritis - Wikipedia

    en.wikipedia.org/wiki/Gastritis

    Blood tests: Blood cell count; Presence of H. pylori; Liver, kidney, gallbladder, or pancreas functions; Urinalysis; Stool sample, to look for blood in the stool; X-rays; Endoscopy, to check for stomach lining inflammation and mucous erosion; Stomach biopsy, to test for gastritis and other conditions [27]

  8. Atrophic gastritis - Wikipedia

    en.wikipedia.org/wiki/Atrophic_gastritis

    Recent research has shown that autoimmune metaplastic atrophic gastritis (AMAG) is a result of the immune system attacking the parietal cells. [6] Environmental metaplastic atrophic gastritis (EMAG) is due to environmental factors, such as diet and H. pylori infection. EMAG is typically confined to the body of the stomach.

  9. Achlorhydria - Wikipedia

    en.wikipedia.org/wiki/Achlorhydria

    Bacterial overgrowth may cause false-positive H. pylori test results due to the change in pH from urease activity. [11] Small bowel bacterial overgrowth is a chronic condition. Retreatment may be necessary once every 1–6 months. [12] Prudent use of antibacterials now calls for an antimicrobial stewardship policy to manage antibiotic ...
