What is the best test for H. pylori?
The stool antigen test and urea breath test are recommended for the diagnosis of an H. pylori infection and for the evaluation of the effectiveness of treatment. These tests are the most frequently performed because they are fast and noninvasive.
Is biopsy necessary for H. pylori?
This is the most accurate way to tell if you have an H pylori infection. To remove the tissue sample, you have a procedure called endoscopy. The procedure is done in the hospital or outpatient center. Usually, a biopsy is done if endoscopy is needed for other reasons.
Are biopsies always done during endoscopy?
In my experience, biopsies are taken whenever any endoscopy is performed, either of something specific or, if nothing is seen, randomly, to look for signs of, for example, inflammation. It’s usual to be told immediately if something is found, otherwise, it’s the wait for biopsy results.
Why are biopsies taken during endoscopy?
Your doctor might use upper endoscopy to obtain a biopsy (small tissue samples). A biopsy helps your doctor distinguish between benign (non-cancerous) and malignant (cancerous) tissues.
Can H. pylori be missed in a biopsy?
H pylori is more likely to be missed if the classical histological picture is not present on the hematoxylin and eosin sections (31). This is particularly exaggerated with PPI use, for which bacterial density is low and typically more proximal (21,22) (Figure 4).
When should a biopsy be done?
A doctor should recommend a biopsy when an initial test suggests an area of tissue in the body isn’t normal. Doctors may call an area of abnormal tissue a lesion, a tumor, or a mass. These are general words used to emphasize the unknown nature of the tissue.
What does testing positive for H pylori mean?

A negative test result means that it is unlikely that you have an H. pylori infection and your signs and symptoms may be due to another cause.
Can a blood test find out if you have H pylori?
