Breath Test Could be Possible for Drugs and Disease

Testing for drug use and disease in humans could soon be much simpler, thanks to new research. Whereas drug tests currently rely on blood or urine samples, researchers have identified a method for drug testing by analyzing various compounds in exhaled breath. 
 
Lead author Dr Göran Ljungkvist said: "Exhaled breath contains particles carrying non-volatile substances. The main components, lipids and proteins, are derived from the respiratory tract lining fluid. The collection procedure is non-invasive, can be repeated within a short time span and is convenient. The small mass sampled is, however, an analytical challenge. Nevertheless, exhaled particles are a new and promising matrix for the analysis of biomarkers.
