New medicine could reduce number of infant deaths from AIDS
This special collection of The Journal of Applied Laboratory Medicine features research on one such test for concussion, a blood test that accurately identifies elderly concussion patients who do not have brain tissue damage. This test could greatly improve triage for elderly concussion patients, enabling clinicians to focus on cases that require urgent treatment such as surgery. This test was also previously validated for use in younger adults, and when this earlier research came out, a popular misconception arose that the test could determine whether it was safe for an athlete to return to play after receiving blunt head trauma. A review in this special collection seeks to educate consumers on why a triage test-;as important as it is-;can't be used for this purpose, and provides expert insight into the search for a blood test that could diagnose concussed athletes on the field.
Concussion patients represent a heterogeneous population, including older adults, young athletes, and small children. Diagnosing and treating these very different patients poses a diagnostic challenge for physicians, who must quickly decide whether to pursue imaging, whether to escalate care, as well as when to discharge and to advise 'return to play. As a result, many biomarkers have been investigated, from decision-support scales to imaging to blood biomarkers." Leslie M.
