Study design: A multicenter, open-label study. The primary endpoint analysis was conducted to determine the sensitivity and specificity of the BreathTek UBT UHR to the composite reference method criteria for the 176 evaluable cases. The table demonstrates the diagnostic performance of the BreathTek UBT (expressed as UHR) compared to the composite reference method criteria in pediatric patients ages 3 to 17 years.

When using BreathTek UBT, false negative test results may be caused by:

  • Ingestion of proton pump inhibitors (PPIs) within 2 weeks prior to performing the BreathTek UBT. If a negative result is obtained from a patient ingesting a PPI within 2 weeks prior to the BreathTek UBT, it may be a false negative result and the test should be repeated 2 weeks after discontinuing the PPI treatment. A positive result for a patient on a PPI could be considered positive and be acted upon
  • Ingestion of antibiotics, or bismuth preparations within 2 weeks prior to performing the BreathTek UBT
  • Premature POST-DOSE breath collection time for a patient with a marginally positive BreathTek UBT result
  • Post-treatment assessment with the BreathTek UBT less than 4 weeks after completion of treatment for the eradication of H. pylori

False positive test results may be caused by urease associated with other gastric spiral organisms observed in humans, such as Helicobacter heilmannii or achlorhydria. Oral contamination associated with urease-containing bacteria may cause false positive results when not using the straw provided in the BreathTek UBT kit.

For pediatric test results. the UHR results must be calculated. DOB results and the web-based Pediatric Urea Hydrolysis Rate Calculation Application (pUHR-CA) are required to determine pediatric patient test results.

  • The pUHR-CA is available at
  • When accessing the calculator for the first time, you will need to create an account

For in-office sample collection and lab analysis:

  1. Administer the test in your office as you would with adult patients. Click here for Patient Preparation and Test Administration instructions
  2. Complete the pediatric UHR card with the following information—which is needed so that the lab can perform the analysis and UHR result using the web-based pUHR-CA

Breath sample analysis must be performed within 7 days of breath sample collection.
