Hydrogen breath tests are based on the fact that there is no source for hydrogen gas in humans other than bacterial metabolism of carbohydrates. [4] Even though the test is normally known as a "hydrogen" breath test, some physicians may also test for methane in addition to hydrogen. Many studies have shown that some patients (approximately 35% ...
Analyzing breath in real-time has the advantage that potential confounding factors associated with sample handling and manipulation are eliminated. Recent efforts have focused on standardizing online breath analysis procedures based on SESI-MS, and to systematically study and reduce other confounding sources of variability. [29]
The presence of Helicobacter pylori (in peptic ulcer disease) can be tested for with the urea breath test. Exhaled nitric oxide is a breath test that might signal airway inflammation such as in asthma. Breath tests for diseases have been developed for early detection of lung cancer, breast cancer, pulmonary tuberculosis and many others, to ...

[12] This is a relatively new field that holds great promise for direct diagnostics of pathogens, such as Influenza , and for in-vivo monitoring of the respiratory lining fluid ( Respiratory epithelium ...
The hydrogen breath test involves having the patient fast for a minimum of 12 hours then having them drink a substrate usually glucose or lactulose, then measuring expired hydrogen and methane concentrations typically over a period of several hours. It compares well to jejunal aspirates in making the diagnosis of bacterial overgrowth.
In medicine, exhaled nitric oxide (eNO - now commonly known as FeNO) can be measured in a breath test for asthma and other respiratory conditions characterized by airway inflammation. Nitric oxide (NO) is a gaseous molecule produced by certain cell types in an inflammatory response.
