Laboratory and case/control study


This study’s aim is to develop of a point-of-care exhaled-breath analysis instrument that will allow the rapid differentiation of non-bacterial infection, Gram-positive bacterial infection and Gram-negative bacterial infection in children with pneumonia.

Pneumonia is the leading infectious cause of death in children worldwide, accounting for 15% of all deaths of children under five years old. Although the condition can be treated by antibiotics, delayed and ineffective diagnosis means that only one third of children receive the antibiotics they need.

How could this research potentially benefit public / patients?

An effective point of care test for pneumonia would enable rapid, accurate diagnosis, allowing timely administration of appropriate therapies. This in turn will help to alleviate the significant human cost associated with the condition.
