5) Collect the gray Post Ingestion specimen 15 minutes after ingestion of the test drink, but no later than 20 minutes post ingestion. Instruct the patient to hold their breath for 4-5 seconds, and then exhale into the gray Post Ingestion collection bag until the bag is full.

Interpretive Data

A negative result does not rule out the possibility of Helicobacter 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. Ingestion of antimicrobials, proton pump inhibitors, and bismuth preparations during the preceding 2 weeks.

2. Administration of the breath test less than 6 weeks after completion of definitive therapy to eradicate H. pylori.

3. Premature or late collection of the postdose 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 heilmannii.
