Specimen Collection & Preparation

Client Notes:

For Office Collection, please contact Client Response at 260-266-1500 (Option 1) to request the BreathID Hp Collection Kit.   

 


Test Notes:

The BreathID Hp collection kit should not be used until four weeks or more after the end of treatment for the eradication of H. pylori as earlier post-treatment assessment may give false negative results.

The H. pylori stool antigen assay is FDA approved for use on specimens from pediatric patients. Safety and effectiveness has not been established in patients under the age of 3. 

Patient Preparation

The patient should not have taken antimicrobials, proton pump inhibitors, or bismuth preparations within two weeks prior to administering the test.  The patient should have fasted at least one hour before administering the solution.  The Citrica Powder solution contains 84 mg of phenylalanine per packet.  The test may not be suitable for patients with phenylketonuria whose dietary phenylalanine should be restricted.

Collection Instructions:

  1. To collect the baseline breath sample, remove the cap from the mouthpiece of the blue baseline bag.  Instruct the patient to take a deep breath, hold their breath for 4 to 5 seconds, and then exhale directly into the mouthpiece of the blue baseline breath bag until completely full.  If the bag is not full, repeat taking a deep breath, holding their breath for 4 to 5 seconds, and exhaling into the mouthpiece of the blue baseline bag until full.  Replace the cap on the bag mouthpiece and firmly press until it clicks and is securely locked into place.
  2. Dissolve the Citrica Powder and urea tablet in 150 to 200 mL of tap water in a single use drinking cup that is at least 8 oz in capacity.  Stir thoroughly with the provided straw until completely dissolved.  Give the prepared test drink to the patient.  Ensure that the entire solution is drunk through the straw within 2 minutes.
  3. Wait 15 minutes.
  4. After 15 minutes, remove the cap from the mouthpiece of the gray post-ingestion bag.  Instruct the patient to take a deep breath, hold their breath for 4 to 5 seconds, and then exhale directly into the mouthpiece of the gray post ingestion bag until it is full.   If the bag is not full, repeat taking a deep breath, holding their breath for 4 to 5 seconds, and exhaling into the mouthpiece of the gray post-ingestion bag until full.  Replace the cap on the bag mouthpiece and firmly press until it clicks and is securely locked into place.

    Protect from direct sunlight and sharp objects

Clinical Interpretation

Reference Range:

Negative


Test Comments:

Antimicrobials, proton pump inhibitors, and bismuth preparations are known to suppress H. pylori.  Ingestion of these in the 2 weeks prior to H. pylori diagnostic testing may lead to false negative results.  If clinically indicated, the test may be repeated on a new specimen obtained two weeks after discontinuing treatment.  A positive result is still clinically valid.


Methodology:
  • Infra-red Spectrophotometry (IR)

Clinical Significance

The BreathID Hp collection system is intended for use to non-invasively measure changes in the 13CO2/12CO2 ratio of exhaled breath, which may be indicative of increased urease production associated with active Helicobacter pylori infection in the stomach.
