Additional Information: Antimicrobials, proton pump inhibitors and bismuth preparations are known to suppress H. pylori, and ingestion of these within 2 weeks prior to testing may cause false-negative results.

If testing does occur within the 2 week period a positive result is considered accurate, a negative result should be repeated with a new specimen.
