Is a blood test for H. Pylori reliable?

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

Helicobacter Pylori (Definition)

H. pylori is a bacterium which commonly infects the mucus layer in the stomach. It can cause chronic inflammation of the lining of the stomach, and over the course of many years can increase the risk of gastric or duodenal ulcer. It can ...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

H.pylori blood test IGG positive and IGM negative. I didn't treat h.pylori before the test. Do I have h.pylori?

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

This is my h.pylori blood test result. IGG positive 17.95. IGM negative 8.50. do I have h.pylori?

This is my h.pylori blood test result. IGG positive 17.95. IGM negative 8.50. do I have h.pylori?

Likely not: IgG to this organism points to a previous infection, IgM an active or very recent infection which is not the case for you. If you do have gastritis symptoms however, I believe a PCR assay from a stool sample would be the best way to detect it if a culture of the gastric biopsy is not contemplated. ...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

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?

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

H pylori belly pain: I feel constant nausea and pain in the stomach and insomnia. I had blood test in h.pylori and result is positive 3.2 U/ml what I can do? ANS: assuming the two are connected you need to be treated for H. pylori. If pain goes away then good. If not then not H. pylori. But need to be tested to be sure it is gone.

Hi, my blood test shows H.pylori (lgA) 25.08, H.pylori (lgG) 11.09 Do I have helicobacter?

H.pylori infection: This is a serology test, which is cheap and convenient to perform. These are antibodies response to H.pylori bacteria, which varies from person to person. It does not means that you have active H, pylori infection. If it is positive it has to be confirmed by endoscopic biopsy or urea breath test (UBT) before starting the treatment. ...Read more

What's the difference between h. Pylori breath test and blood test?

What's the difference between h. Pylori breath test and blood test?

Activity vs antibody: The breath test indicates the presence of active urease splitting organisms (that is h. Pylori) whereas the blood test detects antibodies to h. Pylori which may not actually be present in the body. Two different tests for two different answers. ...Read more

What's the difference between the h. Pylori breath test and the h. Pylori blood test?

What's 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

How accurate is H Pylori blood test to pick up a previous or active infection? Previous test was negative having another one.

Prior infection: The H pylori blood test is best to detect a prior infection because it detects antibodies that the body has formed. To detect an active infection, one of the best (and easiest) methods is to get a stool antigen test performed. This test looks for the actual H pylori bacteria itself. If you had a prior infection but not an active one, it should be negative. ...Read more

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

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

Went to the doctor the other day and she thinks I have gastritis and possibly h pylori so she did a blood test How long do I have to wait for results?

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

Had h pylori blood test 10 years ago - negative. Had another this week for stomach. Negative again. Am I nearly 100% not infected with h pylori?

Why were you tested?: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, you are unlikely to have H pylori.
Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats.
