Patient Preparation, Sample Handling and Transport
The specimen can be stored at 2 - 8 °C for up to 72 hours prior to testing.
Antimicrobials, proton pump inhibitors and bismuth preparations are known to suppress H. pylori and ingestion of these prior to H. pylori testing may give a false negative result. If a negative result is obtained for a patient ingesting these compounds within two weeks prior to a test, it may be a false-negative result and the test should be repeated on a new specimen obtained two weeks after discontinuing treatment.
