A range of pathological conditions can lead to elevated blood ammonia and urea nitrogen levels. These include kidney and liver dysfunction and urea cycle defects. These conditions result in severe reduction in quality and quantity of life. Blood nitrogen levels are controlled by dialysis and monitored using invasive blood tests. Blood nitrogen levels have the potential to be monitored non-invasively in by measuring ammonia in breath. We have developed a device for monitoring human breath ammonia levels.
