The Diagnostic Development Unit (DDU) is a non-invasive disease detection facility, developed by the University of Leicester for use in Leicester Royal Infirmary's A&E department.

It is designed to detect the "sight, smell and feel" of disease without the use of invasive probes, blood tests, or other time-consuming and uncomfortable procedures.

One group of instruments analyses gases present in a patient's breath, a second uses imaging systems and technologies to hunt for signs of disease via the surface of the human body, the third uses a suite of monitors to look inside the body and measure blood-flow and oxygenation in real-time.

University of Leicester researchers from space research, emergency medicine and Chemistry, worked with colleagues in Cardiovascular Sciences, Infection, Immunity and Inflammation, Physics and Astronomy, Engineering, IT Services and the Leicester Royal Infirmary to create the Unit.
