Performance of a Molecular Host Response Assay in Patients Suspected of Sepsis and Stratified by qSOFA

1. In this study, a large percentage of patients initially suspected of sepsis were retrospectively determined to not have sepsis.
2. SeptiCyte® RAPID used alone outperformed other rapid and easily measured markers of sepsis.
3. SeptiCyte® RAPID should be used early in the diagnostic pathway for patients suspected of sepsis to determine likelihood of sepsis. qSOFA, should be used to determine likelihood of poor outcome once a sepsis likelihood has been determined.
4. Rapid and early identification of patients with sepsis using SeptiCyte® RAPID can lead to better management of patients suspected of sepsis.
