H. Pylori Stool Antigen Test

Ordering the H. Pylori Stool Antigen Test

Testing for Helicobacter pylori in stool helps detect an active infection in the digestive tract, which can cause symptoms like stomach pain, bloating, and nausea. This test is often used to check for the bacteria after treatment to confirm if it has been cleared. Interestingly, H. pylori can sometimes be present without causing any symptoms, but it may still lead to stomach ulcers or other digestive issues over time.

Ordering this test can help you and your healthcare provider:

• Find out if H. pylori bacteria are causing your stomach symptoms
• Check if treatment for H. pylori infection has worked
• Reduce the risk of future stomach ulcers by identifying infection early
• Help explain ongoing digestive problems that have not improved with other treatments
• Limit the need for more invasive procedures, like endoscopy, when a stool test is enough

Who Should Consider Digestive Bacteria Screening

People who have had ongoing stomach pain, bloating, or nausea that does not go away may benefit from this test. For example, someone who has tried changing their diet and using over-the-counter remedies but still feels discomfort might want to check for H. pylori infection.

Ordering this test may also be helpful in these situations:

• Someone with a family history of stomach ulcers or stomach cancer
• People who have completed antibiotics for H. pylori and need to confirm the infection is gone
• Those with unexplained iron deficiency anemia
• People who have frequent indigestion that does not improve with antacids
• Someone with unexplained bad breath, as it can sometimes be linked to H. pylori infection

This test can help pinpoint the cause of stomach symptoms and guide the next steps for treatment or follow-up. Delaying this test may allow the infection to continue, which can increase the chance of developing stomach ulcers or other digestive problems. Take the next step to find out if this test is right for your situation.

Preparing for Gastrointestinal Infection Testing

Fasting is not needed before this test, so you can eat and drink as usual. Always follow any instructions your doctor or healthcare provider gives you to make sure your sample is collected the right way and your results are useful.
