Helicobacter pylori (H. pylori) is a type of bacteria. These germs can enter your body and live in your digestive tract. It weakens the stomach's natural protective lining making it more susceptible to damage from gastric acid. After many years, they can cause sores, called ulcers, in the lining of your stomach or the upper part of your small intestine. For some people, an infection can lead to stomach cancer.

Test Results:

2-3 days. May take longer based on weather, holiday or lab delays.

Details:

Certain medications, including antibiotics, proton pump inhibitors (medicines that reduce stomach acid), and bismuth preparations (such as Pepto-Bismol), can suppress H. pylori and may lead to a false-negative test result. If you've taken these within two weeks before an H. pylori stool test, a negative result may not be reliable, and retesting two weeks after discontinuation is recommended. However, a positive result during this time is generally accurate.
