Lung Function & Breathtests

Hydrogen and methane are gases produced in the intestinal lumen by bacteriological breakdown of carbohydrates. The Lactotest 102 and 202 have been developed to provide quick and reliable diagnosis of  gastro-intestinal disorders measuring carbohydrate breakdown deficiencies and/or malabsorption. The technique of exhaled breath hydrogen monitoring is normally well tolerated by patients of all ages. The test is simple, non-invasive and is performed after a short period of fasting (typically 8-12 hours). Many studies have shown that some patients (approximately 35% or more) do not produce hydrogen but actually produce methane. Some patients produce a combination of both gases.

At any moment, you can upgrade your hydrogen Lactotest 102 with other gases like Methane by adding the Lactotest 202 Evolution. The Lactotest 202 Evolution measures also CO2 in the patients' breath to determine if the breath samples that are being analyzed are not contaminated (either with room air or bronchial dead space air).

The Lactotest systems are open and evolutive solution:

The USB communication allows you to interface the equipments to a PC software for database integration, export of results to the Hospital Informatics System (XML, HL7, etc..) or simply print  directly your results in MS Word allowing you to have a perfect integration of results (H2 + CH4 + CO2)  in the patient file.

Applications:

  • Carbohydrate malabsorption detection
  • Carbohydrate breakdown deficiency detection
  • Lactose intolerance diagnosis
  • Bacterial overgrowth diagnosis
  • Transit time diagnosis

Non-invasive:

Non-invasive sampling by end expired gas collection.

Electrochemical Cell:

The H2 electrochemical cell has been carefully developed for the application with lifetimes in excess of 3 years.

CO2 & CH4 Analyzers

Fast Infra-red analyzers allows you to get the results in less than 50 sec ond s and  require minimal maintenance. Warm up time: 30 minutes

Calibration:

Pre-mixed calibration gas system 100 PPM CH4  and  H2  + 5% CO2

Low Cost:

Simple modular construction minimizes manufacturing and maintenance costs.
