Can I take the BreathTek UBT for H. pylori if I’ve taken antibiotics recently?

Taking antibiotics within 2 weeks prior to this test could cause inaccurate results. People should not take PPIs, antibiotics, or bismuth preparations at least 2 weeks prior to being tested.

Can I take the BreathTek UBT for H. pylori if I’ve taken proton pump inhibitors (PPIs) recently?

People should not take PPIs, antibiotics, or bismuth preparations at least 2 weeks prior to being tested. Taking PPIs such as Aciphex® (rabeprazole), Nexium® (esomeprazole), Prevacid® (lansoprazole), Prilosec® (omeprazole), Prilosec OTC® (omeprazole), Protonix® (pantoprazole), Zegerid® (omeprazole/sodium bicarbonate), and Dexilant® (dexlansoprazole) in less than 2 weeks prior to this test could cause a false negative result.7 This means that although you are infected, the test would not reveal that the infection is positive. You would need to repeat the test 2 weeks after discontinuing the use of all PPIs. If you are taking a PPI within 2 weeks prior to testing, a positive result could be considered positive and be acted upon.
