Collection Instructions:Use BreathTek UBT kit (ARUP supply #51124); available online through eSupply using ARUP Connect or contact ARUP Client Services at (800) 522-2787.

  • Information required: Record weight, height, gender and age.
Patient Preparation:This test requires the pediatric patient (3-17 years old) to fast and abstain from smoking for 1 hour prior to test administration. The patient should not have taken antibiotics, proton pump inhibitors (e.g. Prilosec, Prevacid, Aciphex, Nexium) or bismuth preparations (e.g. Pepto-Bismol) within the previous 14 days. The effect of histamine 2-receptor antagonists (e..g., Axid, Pepcid, Tagamet, Zantac) may reduce urease activity on urea breath tests and should be discontinued for 24-48 hours before the sample is collected.

When used to monitor treatment, the test should be performed four weeks after cessation of definitive therapy. The patient should be informed that the Pranactin-Citric drink that will be administered contains phenylalanine. Phenylketourics restrict dietary phenylalanine.
Causes for Rejection:Under-inflated bags. Specimens from patients younger than 3 years old. Refrigerated or frozen specimens.

Reference Range: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. Know causes of false negative results include:
  • Use of antibiotics, proton pump inhibitors and bismuth preparations during the preceding 2 weeks.
  • Administration of the breath test less than 4 weeks after completion of definitive therapy to eradicate H. pylori.
  • Premature or late collection after the post-dose specimen.

Known causes of false positive results include:
  • Patients with achlorhydria
  • Rinsing the test solution in the mouth, which can allow contact with urease-positive bacteria.
  • The presence of other gastric spiral organisms such as Helicobacter heilmanii.
Limitations:For valid result, the post-breath specimen must be collected between 15 and 30 minutes after the patient drinks the Pranactin-Citric solution.
Use:Use to diagnose H. pylori infection in children and adolescents (3 to 17 years of age). For adults, refer to Helicobacter pylori Breath Test, Adult.
