Abstract
The present invention relates to a diagnostic method and breath-testing device for the diagnosis of Celiac Disease or other gastrointestinal malabsorption in adults and children, and uses a hydrogen selective sensor in the form of a ZnO nanowire-based sensor fabricated using a focused ion beam (FIB/SEM) instrument or a thin film.
Claims34
A detector for detecting gastrointestinal malabsorption, comprising a hydrogen selective sensor which detects the presence of hydrogen in breath, which thereby detects the presence of gastrointestinal malabsorption.
A method of detecting gastrointestinal malabsorption using a hydrogen selective sensor which detects the presence of hydrogen in breath, which thereby detects the presence of gastrointestinal malabsorption.
A detection for detecting the presence of hydrogen in breath, comprising:
- a hand-held portable housing;
- a sensor in the housing for detecting the presence hydrogen in a concentration sufficiently low to detect, from a user's breath, the presence of celiac disease;
- an electronic circuit connected to the sensor for providing an output representative of the concentration of hydrogen detected;
- and
- an output display for displaying a visual signal in response indicating the concentration of hydrogen detected.
