Abstract: Disclosed herein are methods that aid in the determination of whether to perform one or more advanced magnetic resonance imaging (MRI) procedures for a head injury by determining the presence or amount of one or more biomarkers in a sample obtained from the human subject. Also disclosed are methods of aiding in the diagnosis and evaluation of a human subject that has sustained or may have sustained an injury to the head, e.g., by assessing biomarker levels in combination with advanced MRI procedures. Further, also disclosed are methods of predicting or aiding in the prediction of the outcome of human subjects that have suffered a traumatic brain injury (TBI) as well as determining the course of treatment or efficacy of a course of treatment for a human subject who has suffered a TBI, e.g., by assessing biomarker levels in combination with advanced MRI procedures.

Abstract: Disclosed herein are methods that aid in the determination of whether a subject has a traumatic brain injury (TBI) by detecting levels of at least one biomarker, such as ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) glial fibrillary acidic protein (GFAP), or a combination thereof, in samples taken from a subject, such as a human subject, where the subject has received a head CT scan that is negative for a TBI.

Abstract: Disclosed herein are methods, and kits for use in said methods, that aid in the diagnosis and evaluation of a subject that has sustained an orthopedic injury and sustained or may have sustained an injury to the head, such as mild traumatic brain injury (TBI), using ubiquitin carboxy-terminal hydrolase L1 (UCH-L1), glial fibrillary acidic protein (GFAP), or a combination thereof. Also disclosed herein are methods, and kits for use in said methods, that aid in determining whether a subject that has sustained an orthopedic injury and sustained or may have sustained an injury to the head would benefit from and thus receive an imaging procedure, such as MRI or head computerized tomography (CT) scan based on the levels of GFAP and/or UCH-L1. These methods involve detecting levels and changes in levels of GFAP and/or UCH-L1 in biological samples taken from a subject at time points within 48 hours after the subject has sustained or may have sustained an injury to the head.

Abstract: The present disclosure relates to methods for diagnosing and evaluating a subject that has sustained or may have sustained an injury to the head, such as a traumatic brain injury (TBI). In particular, the present disclosure identifies various biomarkers, the detection and/or differential expression of which can be used to assess the presence or absence of a TBI in a subject, and can be used as a basis for diagnosing a subject as having a specific type of TBI (e.g., severe TBI or subclasses of mild TBI). The various TBI biomarkers can be detected individually or in combination and can be used as an important diagnostic, prognostic, and/or TBI risk stratification tool as part of assessing a subject's TBI status.

Abstract: Disclosed herein are methods of aiding in the diagnosis and evaluation of a subject that has sustained or may have sustained an injury to the head. For example, the present disclosure provides methods for aiding in the diagnosis and evaluation of a subject to determine whether the subject has sustained a traumatic brain injury (TBI) by detecting or measuring a combination of the levels of ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) and glial fibrillary acidic protein (GFAP) in samples taken at various time points within 48 hours after the subject has sustained or may have sustained an injury to the head.

Abstract: Disclosed herein are methods that aid in the hyperacute diagnosis and evaluation of a human subject that has sustained or may have sustained an injury to the head, such as mild or moderate, severe, or moderate to severe traumatic brain injury (TBI), using an early biomarker, such as ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) glial fibrillary acidic protein (GFAP), or a combination thereof. Also disclosed here are methods that aid in the hyperacute determination of whether a human subject that has sustained an injury or may have sustained to the head would benefit from and thus receive a head computerized tomography (CT) scan based on the levels of UCH-L1. These methods involve detecting levels of early biomarker, such as ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) glial fibrillary acidic protein (GFAP), or a combination thereof, in samples taken from a human subject at a time point within about 2 hours, such as about 10, 12, or 20 minutes, after the subject has sustained or may have sustained an injury to the head.
