Useful For

Diagnostic testing for Helicobacter pylori infection in patients suspected to have active H pylori infection

 

Monitoring response to therapy

 

This test is not appropriate for asymptomatic people.

Testing Algorithm

Specimen Type

Breath


Ordering Guidance


An alternative test for the diagnosis of active Helicobacter pylori infection in patients is the HPFRP / Helicobacter pylori with Clarithromycin Resistance Prediction, Molecular Detection, PCR, Feces, which requires a different collection.



Specimen Required


Patient Preparation:

1. Patient should be fasting for 1 hour.

2. Do not administer this test if this list of instructions is not followed, as test results may be inaccurate:

a. Do not administer this test if patient is allergic to citric acid.

 Note: Product contains aspartame.

b. Patients should not take proton-pump inhibitors (eg, Prilosec, Prevacid, Aciphex, Protonix, and Nexium) or bismuth compounds (eg, Pepto-Bismol) for 2 weeks prior to testing.

c. Patients should not take antibiotics for 4 weeks prior to testing.

d. Histamine 2-receptor antagonists (H2RA), such as Pepcid, Tagamet, Axid, or Zantac may impact the sensitivity of the test and, if possible, should be discontinued for 2 weeks prior to testing.

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

 

Supplies: H. Pylori Breath Kit - Meridian BreathID (T906; fees apply)

Collection Instructions:

1. Do not collect if patient is younger than 3 years of age.

2. Follow instructions included with kit.

3. Mixing the (13)C-Urea Tablet

a. Dissolve the Citrica and the (13)C-enriched urea tablet in 150 to 200 mL (5.1 to 6.8 oz.) of tap water in the provided drinking cup.

b. Close the lid firmly using both hands. Place fingers over lid and shake thoroughly for a few minutes, until the Citrica Powder and the urea tablet are completely dissolved.

Note: Tiny particles may remain visible after thorough mixing. However, if more substantial particulate matter is still present after five minutes of mixing, discard the solution and repeat the procedure with a new kit.

Method Description

In the Helicobacter pylori urea breath test, 75 mg (13)C-urea tablet and 4.3 g Citrica powder are dissolved in water, and the resulting solution is ingested by the patient. The presence of the Citrica creates an acidic environment in the stomach and delays the transfer of the ingested solution to the duodenum. These 2 characteristics facilitate the decomposition of the urea by H pylori, if present. Thus, in the presence of urease associated with gastric H pylori, (13)C-urea is decomposed to (13)CO2 (carbon dioxide) and ammonia.

 

The (13)CO2 is absorbed into the blood and then exhaled in the breath. Absorption and distribution of (13)CO2 is fast. Therefore, the cleavage of urea by the H pylori urease that produces the (13)CO2 occurs immediately after the solution is ingested and enables immediate detection of increased (13)CO2 in the exhaled breath of H pylori-positive patients. In the case of H pylori-negative patients, the (13)C-urea does not produce (13)CO2 in the stomach because there are no human enzymes that can decompose the urea in the stomach.(Package insert: IDkit Hp Two for Exalenz BreathID Hp Lab System.
