UBT - Specimen: Helicobacter pylori Breath Test

Test Catalog

Test ID: UBT    
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

Breath

Advisory Information

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

Necessary Information

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

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.

Patient Preparation:

1. Fasting 1 hour.

2. 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. If these instructions are not followed, test results may be inaccurate.

3. Histamine 2-receptor antagonists (H[2]RAs) such as Pepcid, Tagamet, Axid, or Zantac should be discontinued for 24 to 48 hours before the BreathTek UBT test is administered. If these instructions are not followed, test results may be inaccurate.

4. Carafate (sucralfate) does not interfere with the test. Use of antacids does not affect the accuracy of this assay.

Supplies: H. Pylori Breath Kit (T375: fees apply)

Collection Instructions:

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

2. Follow instructions included with kit.

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.
