The purpose of this study is to assess if putative brain injury biomarkers have utility as blood-based traumatic brain injury (TBI) diagnostic and monitoring tools. This will be accomplished by examining the relationships between potential serum-based TBI biomarkers and clinical measures of injury severity, occurrence of complications, and outcome, in subjects with mild or moderate TBI. The assay will be evaluated in a sample population of subjects over the age of 18 who have been referred to the health care provider for closed head injury evaluation.

Condition Intervention

Primary Outcome Measures:
  • Assessment of putative TBI markers relative to diagnosis [ Time Frame: within 24 hours and at Day 35 ]

Secondary Outcome Measures:
  • Assessment of correlation between putative TBI marker levels and severity of TBI and neuropsychological outcome (per RPQ and ImPACT) [ Time Frame: within 24 hours and at Day 35 ]

Other Outcome Measures:
  • Assessment of pituitary status and determination of the presence of autoantibodies [ Time Frame: Day 35 ]
