Gastric tissue biopsy is the removal of stomach tissue for examination. A culture is a laboratory test that examines the tissue sample for bacteria and other organisms that can cause disease.
The tissue sample is removed during a procedure called upper endoscopy (or EGD). It is done with a flexible tube with a small camera (flexible endoscope) at the end. The scope is inserted down the throat into the stomach.
The health care provider sends the tissue sample to a laboratory where it is examined for signs of cancer, certain infections, or other problems.
Follow instructions on how to prepare for the procedure. You will likely be asked not to eat or drink anything for 6 to 12 hours before the procedure.
Your provider will tell you what to expect during the procedure.
This test may be done to diagnose a stomach ulcer or the cause of other stomach symptoms. These symptoms may include:

A gastric tissue culture may be considered normal if it does not show certain bacteria. Stomach acids normally prevent too much bacteria from growing.
Abnormal results may be due to:
Your provider can discuss the risks of the upper endoscopy procedure with you.
