- Campylobacter pylori
- Campylobacter From Stomach
- H pylori Culture
- Culture, Helicobacter pylori
Test Includes
Culture; smear for modified Gram stain (reported only if positive and culture does not grow); isolation and identification (additional charges/CPT code[s] may apply). CPT coding for microbiology and virology procedures often cannot be determined before the culture is performed.
Expected Turnaround Time
8 - 10 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Culture
Additional Information
For optimal recovery of Helicobacter pylori, it is strongly recommended that culture be performed within three hours of specimen collection. Helicobacter pylori has been implicated as a factor associated with chronic gastritis. The clinical significance of the organism in regard to gastric or duodenal ulcers, dyspepsia, and gastric carcinoma remains unclear.1 Other factors, such as pepsin, nonsteroidal anti-inflammatory agents (NSAIDs), aspirin, ischemia, stress, alcohol, and bile salts as well as H pylori, all may have a role in altering the material mucosal barrier. The relative etiologic role of H pylori remains a subject of speculation. H pylori is hypothesized to secrete products capable of degrading gastric mucin. The organism may be seen in Gram stains on imprints from tissue biopsies. In one study, imprint Gram stains performed by imprint technique on biopsies from both the antrum and fundus yielded positives in 100% of 32 culture-positive cases.2
