  • Publication number: 20250020666
    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.

  • Publication number: 20250020665
    Abstract: Disclosed herein are methods that aid in the determination of whether to perform imaging, such as magnetic resonance imaging (MRI) or computerized tomography (CT) scan, on a human subject that has sustained or may have sustained an injury to the head using an early biomarker, such as ubiquitin carboxy-terminal hydrolase L1 (UCH-L1), glial fibrillary acidic protein (GFAP), or a combination thereof. These methods involve detecting levels and changes in levels of UCH-L1 in samples taken from a human subject at time points within 24 hours after the subject has sustained or may have sustained an injury to the head.

  • Publication number: 20250003988
    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.

  • Publication number: 20240426842
    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.

  • Publication number: 20240337668
    Abstract: Disclosed herein are methods that aid in the determination of whether a subject has or may have sustained an acquired brain injury, such as a traumatic brain injury (TBI), by detecting levels of at least one biomarker, glial fibrillary acidic protein (GFAP), in one or more samples taken from a subject, such as a human subject.

  • Patent number: 12105100
    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.
