Is it true the most accurate test for h pylori is having a stool sample and not blood test?

Testing for H.pylori: H.Pylori status is checked with the intention of treating the infection to eradication, when found. If persistent or recurrent, please ask your doctor to prescribe a drug combination different than your initial regimen--your h.Pylori may be resistant to the first antibiotics used. Serology alerts us to past infection; stool testing, breath testing, stomach biopsy identify active bacteria. ...Read more

I had h pylori about 5 years ago. I was feeling sick again and my blood antibody tested positive but my stool test was negative. Do I have it?

No: The blood test can be positive for years and can be affected by a number of meds. The stool test is much more accurate and less affected by medications. If the stool test was negative then you likely don't have the infection. ...Read more

blood test IGG 17.95 positive and IGM 8.50 negative. Stool test was negative. Do I infect with h.pylori?

Past infection: These results suggest past infection with H. pylori. The blood test can remain positive for years after past infection even if you were treated. The stool test and urea breath test can better detect current infection. The gold standard for testing is a biopsy during endoscopy.

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?

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

Keep looking: With the symptoms that you have I would certainly keep looking. It sounds like pulmonary function tests are in order if you are having trouble breathing. I would recommend the neurology consult for your dizziness. Ask your doctor if gastroparesis has been ruled out and whether ger d has been ruled out. Sometimes stomach pain can be from a pinched nerve in the back. That's something also that the neurologist could evaluate. ...Read more

My 7 year old girl found h-pylori +ve in blood but -ve in stool is it necessary to go for endoscopy or go for only eradication?

Go invasive at last: Blood test for H pylori can remain positive for long time after the infection. Also, negative stool test can be falsely negative. The main criteria to go forward should be the (persistence of) symptoms in your child and what treatment has been tried with what effect. I would repeat stool antigen, consider breath hydrogen test, and one proper full treatment before subjecting child to endoscopy etc ...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

H Pylori: Avoid proton pump inhibitors such as Omeprazole and also drugs such as pepto bismol (bismuth subsalicylate) and most antibiotics. I would avoid these for at least 3-4 days. Personally I prefer the h pylori breath test that can be done at most larger labs. ...Read more

Is a blood test for H. Pylori reliable?

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

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
