  • Identification and analysis of protein biomarkers
    Patent number: 11774457
    Abstract: Protein biomarkers may be used to rapidly and accurately diagnose stroke. Biomarkers may be utilized in a rapid and inexpensive test that could be used at the bedside or ambulatory setting to definitively indicate the presence or absence of stroke and its severity. Such a test would quickly stratify patients in need of immediate stroke treatment from those who are not having a stroke. The test may aid emergency personnel in the decision for the most appropriate treatment plan and treatment location, thereby minimizing morbidity and mortality of stroke patients.
    Type: Grant
    Filed: July 9, 2019
    Date of Patent: October 3, 2023
    Assignee: Wright State University
    Inventors: James Edwin Olson, April Daubenspeck, David Cool, Bryan Ludwig
