Basics of 13C Breath Testing

Breath Tests are a new non-invasive technique, which offer real benefits to both patient and doctor. A range of tests is available to clinicians for gastro-intestinal and metabolic diseases. Breath Tests use metabolites labeled with a
non-radioactive isotope of carbon, which removes the environmental and safety concerns associated with radioactive materials, while obtaining definitive results.

A 13C Breath Test consists of the administration to a patient of a 13C labeled substrate that is metabolized by a specific enzyme system resulting in 13CO2 as the end product. To monitor the enzyme response, 13C enrichment is measured in breath CO2.

The total procedure of 13C Breath testing includes definition of the preparation of the patient before the test,
administration of the 13C labeled substrate, collection of breath samples, measurement of 13C enrichment in breath CO2 and calculation of an end result.

To detect the Helicobacter pylori bacteria in the stomach, the Urea-13C Breath Test is used.

Basics of H2 and CH4 Breath Testing

Hydrogen and methane are produced in the digestive system primarily only by the bacterial fermentation of carbohydrates (sugars, starches or vegetable fibers), so either of these gases appear in the expired air, it is usually a signal that carbohydrates or carbohydrate fragments have been exposed to bacteria, permitting such fermentation to take place.
 Bacteria are ordinarily not present in significant numbers in the small intestine, where digestion and absorption of sugars take place. Therefore, when a challenge dose (eg. lactose) is ingested, the level of hydrogen in alveolar air will rise significantly within one to two hours (depending on the intestinal transit time) only if the sugar is not digested and, therefore reaches the colon.
