What’s the h. Pylori breath test?

What’s the h. Pylori breath test?

See below: The test that i think of for breath testing is for helicobacter pylori, which is a bacterial infection of the stomach that can cause gastritis or stomach ulcers. This test is accurate and currently seems to be preferred over blood testing for h. Pylori. There have been some breath testing for intestinal bacterial overgrowth problems, but I do not know if it is performed much anymore. ...Read more

Chronic gastritis; chronic duodenitis, hyperemic gastric mucosa; positive helicob. Pylori stool test. Do i need treatment for helicobacter pylori?

Erosive gastritis. h.pylori blood test positive, breath test positive, stool antigen test negative, biopsy negative. what to do ?

Erosive gastritis. h.pylori blood test positive, breath test positive, stool antigen test negative, biopsy negative.  what to do ?

Treat it: The positive H. pylori antibody test is not a reliable indicator of current infection. The gold standard for H. pylori treatment is the gastric biopsy, and this is negative in this patient. However, I am impressed by the positive breath test and erosive gastritis. I would have expected stool antigen to be positive, as it mirrors the breath test. Given the discrepant results, treat the patient. ...Read more

Breath test= positive sibo due to double peak hydrogen counts. Egd = duodenal lymphocytosis. Negative celiac. Should i take xifaxin if only symptoms is gas?

Breath test= positive sibo due to double peak hydrogen counts. Egd = duodenal lymphocytosis. Negative celiac. Should i take xifaxin if only symptoms is gas?

It's Worth a Try: There is very little downside in taking xifaxan, (rifaximin) since it is basically a non-absorbable antibiotic. Duodenal lymphocytosis may be a non-specific finding, and if your only symptom is excessive gas, then trying this relatively safe antibiotic might just work. ...Read more

Once someone has progressed to gastric intestinal metaplasia, does a urea breath test still detect H pylori?

Yes: The urea breath test is a rapid method to identify infections by Helicobacter pylori,implicated in gastritis, gastric ulcer, and eventual malignancy based upon the ability of H. pylori to convert urea to ammonia and carbon dioxide. The test measures active H. pylori infection. If antibiotics are depressing the amount of H. pylori present, or the stomach conditions are less acidic than normal, the amount of urease present will be lessened. In many untreated cases of malignancy the H.pylori levels are still relatively high with early malignancy, ...Read more

What is: Focal chronic  peptic-type duodenitis.  H. Pylori negative.

What is: Focal chronic  peptic-type duodenitis.  H. Pylori negative.

Breaking it down...: Focal = a spot, not all over. Chronic = constant, not once-in-a-while. Peptic-type = damaged by exposure to stomach acid. Duodenitis = inflammation/damage of duodenum, the very beginning of the small intestine that actually connects to the end of your stomach. H. Pylori negative = it was not associated with a bacterial infection that is well known to cause ulcers. Hope that is helpful. ...Read more

Helicobacter pylori test, how to interpret results?

Helicobacter pylori test, how to interpret results?

Helicobacter tests: Rapid tests for h. pylori are based on it's fairly unique enzyme urease, producing ammonia. This can be detected in gas (breath test), or pH-based media testing of tissue samples. The best test is a biopsy, perhaps with direct detection by IHC. The latter method also can find other complications like cancer. Stool antigen tests are also available. Serologic tests only tell if you have ever had it. ...Read more

Does basic blood test (cbc) tests for h pylori bacteria?

No: A CBC or complete blood count checks white blood cells, red blood cells, and platelet counts. There is a serologic test for h pylori which can be used to screen for infection, but can not be used after treatment as it can remain positive. A stool test, breath test, or biopsy can be used to check for eradication after treatment. ...Read more

Whats the difference between the h. Pylori breath test and the h. Pylori blood test?

Whats the difference between the h. Pylori breath test and the h. Pylori blood test?

Different: The breath test looks for presence of the active infection and presence of the bacteria in your stomach. It can be used to test to see if you are cured after treatment. The blood test checks for an antibody that is produced by your body after being exposed to the bacteria. It, however, will always be present and cannot be checked to see if you cured the infection. ...Read more
