Helicobacter pylori Breath Test

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

See Helicobacter pylori Diagnostic Algorithm in Special Instructions.

Specimen Type Describes the specimen type needed for testing


Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Container/Tube: Otsuka BreathTek UBT Breath Test Specimen Collection Kit (T375: fees apply)

Specimen Volume: Breath specimen

Collection Instructions: 

1. Fasting (1 hour).

2. Do not collect if patient is <3 years old.

3. For patients between 3 and 17 years old, complete Pediatric UHR Calculation Information card: http://www.breathtek.com/assets/web/pdf/pediatric-card.pdf


Additional Information:

1. Patients should not have taken bismuth/Tritec, antibiotics, proton-pump inhibitors (eg, Prilosec, Prevacid, Aciphex, Protonix, and Nexium) or Pepto-Bismol for 2 weeks prior to testing.

2. If taking prescription levels of the H2-receptor antagonists (Pepcid, Tagamet, Axid, Zantac), it is suggested to move to the low-dose, over-the-counter strength for 2 weeks prior to testing and not taking the dose on the day of the test.

3. Carafate (sucralfate) does not interfere with the test.

4. An alternative test for the diagnosis of active Helicobacter pylori infection in patients younger than 18 years of age is the HPSA / Helicobacter pylori Antigen, Feces which requires a different collection.

Forms: If not ordering electronically, complete, print, and send a Microbiology Test Request Form (T244) with the specimen (http://www.mayomedicallaboratories.com/it-mmfiles/microbiology_test_request_form.pdf).

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

Bag of ''breath'' must be full

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected









Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
