Will proton pump inhibitors (PPI) impact Gut Zoomer results?

Yes. Proton pump inhibitors (PPI) may influence the level of digestion and absorption markers. To avoid PPI impact on markers of digestion and absorption, wait 2-3 days after last use before collecting a sample. Additionally, PPIs can cause false negatives (results indicate 'not detected' but you do actually have it) for Helicobacter pylori. To avoid a potential false negative Helicobacter pylori result, wait 14 days after last use before collecting a stool sample. Consult with your healthcare provider before stopping any medications or supplements.
