A Validation of a Genomics Based Prognostic in Severe Trauma

In the traumatized population (severe blunt traumatic injury), blood samples will be collected at admission, days 1, 4, 7, 14, 21 and 28, or until discharge from the ICU or death. A total of 5 mLs of blood will be collected at admission and day 1, 4 mLs of blood will be collected at each remaining time point.

The healthy volunteer participants will donate a one-time 5 mL blood sample which will undergo rapid leukocyte genomic screening. These controls will allow the investigators to determine if the values obtained are accurate, reliable, and repeatable.
