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

RESULTS FOR H. PYLORI TEST AFTER 4 WEEKS OF THE TREATMENT : BREATH TEST IS NEGATIVE, AND BLOOD TEST IS POSITIVE AND HIGH. WHAT DOES IT MEAN?

RESULTS FOR H. PYLORI TEST AFTER 4 WEEKS OF THE TREATMENT : BREATH TEST IS NEGATIVE, AND BLOOD TEST IS POSITIVE AND HIGH. WHAT DOES IT MEAN?

H Pylori Treatment : Following H Pylori treatment, the most important part of management is to know if a patient is having bloating, or pain suggestive of incompletely treated infection. Urea breath test is often done to determine eradication of the bug; IgG blood test is not helpful after treatment as the test may remain elevated for an indefinite period of time once someone is diagnosed with H Pylori. ...Read more

Dear sir Please help me . I did the stool test, blood test and biospy were negative h.pylori.but breath test was positive.what to do?

Dear sir 
Please help me . I did the stool test, blood test and biospy were negative h.pylori.but breath test was positive.what to do?

Strange: I assume the doctor ordered these tests to evaluate your "heartburn," which is confusing to me. H. pylori is a bacterium that can cause chronic antral gastritis or peptic ulcer disease. I would have an extremely low pretest probability for either of these diseases in a 28 year-old. The breath test yields few false positives. The other tests are very sensitive, with very few false negatives. ...Read more

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

Two different tests for two different answers. ...Read more

Can the urea breath test for h-pylori cause diahrrea. I had to drink a citrus type drink. Not sure what it had in it.

Can the urea breath test for h-pylori cause diahrrea. I had to drink a citrus type drink. Not sure what it had in it.

Unlikely: For the swallow urea labelled with either radioactive carbon-14 or non-radioactive carbon-13. Subsequently the detection of isotope-labelled carbon dioxide in exhaled breath due to splitting of urea indicates that urease is present in the stomach, and therefore that h. Pylori bacteria are present. This should not produce diarrhea. ...Read more

Im currently taking mastic gum and dgl. Im planning on doing urea breath test for h pylori in a few weeks. Will these supplements interfere the test?

Best to stop them...: While the data on mastic gum and DGL is limited, and while the American Gastroenterological Association does not endorse them as treatments for H pylori, they can potentially interfere with the test. If the mastic gum kills some but not all of the H pylori, this may result in a "false negative" test. In other words, the test may state you don't have H pylori but in fact you still do. ...Read more

Probiotics & Hpylori: Here's a reference that indicates that some probiotics may improve eradication of H.pylori-- thus would be expected to alter pre- and post-antibiotic treatment breath test results. Ref.http://www.medscape.com/viewarticle/763163 ...Read more

What is the likelihood of missing h-pylori on various tests 2-3 times? For the breath test I didn't use PPIs or H2 blockers for 1 week prior.

Tests for H. Pylori.: Granted, some tests are more accurate and reliable than others, but most tests repeated three times should have sufficient accuracy to give us confidence in a negative result. That being said, the EGD with biopsy would likely be the most definitive. ...Read more

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
