Measuring Auto-fluorescence of White Corpuscles for the Early Diagnosis and the Monitoring of Pneumonia in ICU (BIONAGA)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02717767
Recruitment Status : Completed
First Posted : March 24, 2016

Nantes University Hospital

Brief Summary:
The diagnosis of pneumonia is challenging in Intensive Care Unit. The auto-fluorescence of white corpuscles is altered during pneumonia. In presence of bacterial growth on lung samples, the measure of autofluorescence of white corpuscles could help the clinicians to discriminate bacterial colonization from acute infection.
