1. Blood tests.
This test is used to check for the presence of H. pylori antibodies in the blood. A positive test indicates that the patient has been in contact with the bacteria at some time in their lives, but it does not indicate that the patient is infected. Blood tests may also be done to check for anemia, which occurs due to gastric bleeding due to gastritis.
2. Breathing tests.
This test can determine whether a patient is infected by the bacteria H. pylori or not.
3. Feces Test.
This test checks whether there is H. pylori in the feces or not. A positive result could indicate infection. Test conducted for the presence of blood in the stool. It showed bleeding in the stomach.
4. The upper gastrointestinal endoscopy.
With this test can look for abnormalities in the upper gastrointestinal tract which may not be visible on X-rays. This test is done by inserting a small flexible hose (endoscope) through the mouth and into the esophagus, stomach and upper small intestine. Throat advance in anesthesia before the endoscope is inserted to ensure patients feel comfortable undergoing this test. If any tissue in the gastrointestinal tract looks suspicious, the doctor will remove a small sample (biopsy) of the tissue. The samples will then be taken to the laboratory for examination. This test takes approximately 20 to 30 minutes. Patients usually do not go home when the test is completed, but had to wait until the effects of anesthesia disappear, approximately one or two hours. Virtually no risk as a result of this test. Frequent complication is the discomfort of the throat from swallowing the endoscope.
5. X-rays of the upper gastrointestinal tract.
This test will look for signs of gastritis or other gastrointestinal diseases. Usually it will be asked to swallow a liquid barium X-ray done before. This liquid will coat the gastrointestinal tract and be seen more clearly when in the X-ray.
