HostDx Sepsis in Patients With Acute Respiratory Infections

This study will analyze gene expression data (HostDx Sepsis test) from blood samples collected from participants with suspected respiratory infections. The primary endpoint of the study is to prospectively validate the HostDx Sepsis test for infections. As a secondary endpoint the correlation of participant prognosis and gene expression results in the HostDx Sepsis test will be validated. Participants presenting to the emergency departments of enrolling sites with a suspected bacterial or viral respiratory infection and 2+ vital signs are meeting enrollment criteria.


This research study is led by Dr. Jay Steingrub.
