Why Test for H. pylori?
Testing for H. pylori is essential in patients with duodenal ulcers. Identifying the infection can guide treatment and prevent recurrence. Knowing your H. pylori status helps tailor the right therapeutic approach for effective management.
Common Testing Methods
Several tests can detect H. pylori, including breath, stool, and blood tests. Each method has its pros and cons, with breath and stool tests being preferred for accuracy. Endoscopic biopsy remains a definitive test, often used when others are inconclusive.

Interpreting Test Results
Positive results indicate an active H. pylori infection, requiring treatment. Negative results need careful evaluation, especially if symptoms persist. False negatives can occur, so further testing might be necessary to rule out infection.
