Breath Test Vs Blood Test For H Pylori
Yes, initially : The H. Pylori blood test is >90% sensitive and specific for H. Pylori infection in the past. It is best used to diagnose the early/initial stages of infection. The only limitation is that the blood test remains positive for quite a while after successful treatment for H. Pylori, so it should not be used as a marker for eradication. ...Read more
No: A CBC or complete blood count checks white blood cells, red blood cells, and platelet counts.

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
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

H.pylori blood test IGG positive and IGM negative. I didn't treat h.pylori before the test. do I have h.pylori?
Hard to know: I believe that the prevalence of H. pylori is much higher in Phnom Penh than in most of the United States. Without knowing any specifics about the test that was used, I suspect the positive predictive value is high considering your location. This is increased given your history of gastritis. Treatment is straightforward and effective and should be considered. ...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?
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
