How can ulcer biopsies NOT be positive for Pylori

Waiting on my biopsy results and Im confused. If most of us (or at least a good percentage) have Pylori in our stomachs - how can a test tell the difference between an actual Pylori case and the "presence" of it. Is there a high number in a biopsy? How does this work.
Hope Im being clear. Thanks

Because there's a difference between active and inactive chronic gastritis. Active chronic gastritis means that h.pylori is present as immune cells try to eliminate the bug. Inactive means there's no h.pylori hence there's no immune cells at the biopsy result.

So the biopsy is not looking for h pylori but immune cells? OK

No, biopsy detect h.pylori, there's a method called immunohistochemistry that is used for detection.

great explanation.
you can do specific immuno stain to detect H. pylori directly. It's made up of special antibody that target specifically at H. pylori. So the pathologist can see H. pylori.
However, the immune response, active gastritis, already good enough to give a hint that there is pathogen. Since H. pylori is almost always the reason for the gastritis, many pathologists do not go ahead to do further staining.

Biospsy came back negative for pylori - though I have 2 small ulcers.
Could medicine type ulcers create gas/heartburn symptoms?
I feel like crap and was hoping for a diagnosis. Now Im at square 1

Are you saying your ulcers are caused by medicine, such as NSAIDs?
yea, when your stomach has ulcers, it act weirdly and produce gas and give heartburn symptoms.
Just take PPI for a month and see if that helps.

Im a bit concerned because even though my biopsy came up negative for pylori - my doctor has me on ppis to clear up the ulcer. Ultimately Id like to do a breath test - but if i stay on PPIS for a month it will be nasty to come off of them.
Also my doctor said "PPIs for a month will clear up the ulcer" which - I believe is far too short a time to clear up 2 ulcers. So Im definitely confused by his statement.
Anyway - I hope its OK to reach out like this. Thanks much.

it's a standard protocol to take PPI for a month to help the ulcer to heal. If you think it's not enough, you can continue for another month.
It's not urgent to get a diagnostic of H. pylori quickly. You can do follow up the H. pylori test when you are absolutely ready.
