Abstract

Detection of Pathogens in Blood for Diagnosis of Sepsis and Beyond

Highlights

  • Determining whether a patient has a microbial infection is a common clinical challenge

  • Diagnosis of sepsis and administration of antibiotics is vital because progression to severe sepsis or septic shock has serious consequences (Angus and van der Poll, 2013)

  • Developments in PCR and mass spectrometry have increased the likelihood of identifying bacteria in blood samples, but often rely on time-consuming pre-analytical processing such as blood culture in order to increase pathogen load

Summary

Introduction

Determining whether a patient has a microbial infection is a common clinical challenge. In this issue of EBioMedicine, Cartwright et al describe a rapid blood test to discriminate between patients with microbial infections and those with sterile trauma (Cartwright et al, 2016). Detecting bacterial infections in blood is a key step in the diagnosis of sepsis, and initiating treatment with antimicrobials (Deutschman and Tracey, 2014; Cohen et al, 2015).
