Breath Test, H. pylori
|Stability:||Ambient: 2 Week(s); Refrigerated: Unacceptable; Frozen: Unacceptable; Incubated: Unacceptable|
|Interpretive Data:||General Reference Range : negative |
A negative result does not rule out the possibility of H. pylori infection. If clinical signs are suggestive of H. pylori infection, retest with a new specimen or an alternate method.
Known causes of false-negative results include:
1. Use of antibiotics, proton pump inhibitors, and bismuth preparations during the preceding 2 weeks.
2. Administration of the breath test less than 4 weeks after completion of definitive therapy to eradicate H. pylori.
3. Premature or late collection of post-dose specimen.
Known causes of false-positive results include:
1. Patients with achlorhydria.
2. Rinsing the testing solution in the mouth or not using the straw provided in the kit, which can allow contact with urease-positive bacteria.
3. The presence of other gastric spiral organisms such as Helicobacter heilmanii.
