Shipping Hydrogen-Methane Test


Shipping Hydrogen-Methane Test



How is the breath test performed?
The patient takes in air and blows into a special pouch, and then inserts a glass vial into the mouthpiece. He then consumes 10 grams of lactulose solution, which, as a synthetic disaccharide consisting of galactose and fructose, is not absorbed in the small intestine and is fermented by intestinal bacteria. Lactulose moves down the digestive tract, while bacteria break it down into short-chain fatty acids, hydrogen and carbon dioxide. Hydrogen is dissolved in the blood and is transported to the lungs, where we can test for its presence in exhaled air. The hydrogen can be used by the archeons to produce methane. The patient repeats the exhaled air procedure every 20 minutes over the course of 3 hours. If there is an elevated increase in hydrogen and/or methane in the relevant section of the small intestine, this may indicate bacterial overgrowth in the small intestine SIBO or IMO archeons. The vials are sent to an outpatient clinic, whose staff tests the samples for hydrogen and methane using a Qunintron instrument. The patient receives the result of the test via email within two business days of receiving the samples.

What are the indications for breath testing?
Indications for the test may include excessive bloating, gas, abdominal pain, diarrhea, loose stools, constipation, reflux, heartburn, bad breath, a feeling of overflow, fullness in the epigastrium, headaches and anemia. Symptoms can worsen especially after eating foods such as onions, garlic, leek, cauliflower and apple. After a prolonged period of illness, symptoms may worsen after just drinking a glass of water on an empty stomach.

What are the contraindications to breath tests?
Absolute contraindications are hereditary fructose intolerance and postprandial or reactive hypoglycemia.

Is a referral needed for the test?
