Helicobacter Urease Test
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
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
The blood test for: H. Pylori checks for antibodies against the bacterium. Antibodies are proteins that help your body fight off infection and they may be detectable indefinitely, even for a lifetime. Biopsy & urease tests check for presence of an active infection. (+) H. Pylori blood test with negative biopsy & urease suggests you had the infection in the past but that it's not currently active. ...Read more
H. pylori infection: .. which causes gastritis with symptoms of early satiety, abdominal pain, heartburn. If you are symptomatic, then you will need the treatment. If you are not symptomatic or have responded to treatment already, then your test result indicates ongoing antibody production (normal immune response to previous infection) and no treatment is required. Good luck! ...Read more
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 moreSee 1 more doctor answer

Probably E Coli: There are many dozens of bacteria that can be lactose fermenting gram negative bacilli. This is just a classification scheme based on gram positive or negative; rod (bacillus) or cocci (ball); and what they grow on in a laboratory evaluation. Examples include e. Coli, klebsiella, enterobacter, citrobacter. ...Read more
Can you detect spirochete infections(leptospirosis, borreliosis, syphilis) via blood culture tests? If not, why?
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
Cultures : Await final cultures and sensitivities before determining antibiotics. ...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
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 moreSee 1 more doctor answer
