Collection Processing Instructions

**Submit specimens to the lab ASAP Monday-Thursday, and always within 24 hours of collection.  Any specimen submitted outside these parameters may render it unsuitable for testing due to specimen lability. 

The entire specimen will be submitted for this test; if additional studies are needed, submit additional samples.

Specimens source is required; include the specific anatomic source.

Test Information

Culture-negative results may occur due to the fastidious nature of the organism. Delays in specimen transportation will decrease recovery of the organism. Culture should be set up as soon as possible following specimen collection. Antimicrobial therapy may render the culture negative.

Due to Helicobacter pylori's fastidious nature and slow growth, it may take 7 days to recover the organism and up to an additional 21 days to perform antimicrobial susceptibility testing when requested.

Mayo test code for susceptibility testing is ZMMLS. For Helicobacter pylori: amoxicillin, ciprofloxacin, clarithromycin, metronidazole and tetracycline are tested.

Reference Range Information
Performing Location Reference Range​​
​Mayo Laboratories ​No growth after 7 days
Interpretation

A positive result provides definitive evidence of the presence of Helicobacter pylori.

Organisms may be detected in asymptomatic (colonized) individuals.

False-negative culture results may occur since the organism may die between biopsy collection and laboratory culture.
