Rapid Molecular Detection of Sepsis in Whole Blood

Rapid diagnosis of sepsis is crucial for treatment and survival. Currently, blood culture takes 48 hours-5 days to complete. After starting antimicrobial treatment blood culture results are not reliable. As a result, empirical broad spectrum antimicrobial therapy is mostly used. This implies possible antimicrobial over- or under treatment which is associated with increased antimicrobial resistance development. Early identification of the causative pathogen of sepsis will therefore have a major impact on the adequate treatment and reduction of high mortality rates. To date, there is not a single molecular diagnostic test available on the market to detect all putative causative bacterial pathogens of sepsis. In this study, the investigators will develop and validate a completely new molecular sepsis approach based on pathogen DNA detection, as an alternative to culture.
