Biomarker for Brain Injury - Quiz

[fa icon="calendar'] Oct 14, 2016 5:00:00 AM / by Isadora Guggenheim & Winter Ninivaggi

Blood Biomarkers for brain injury. New blood test is able to detect concussion up to one week later.

It's football season! Concussion rates among football players are high, very high. It is important to detect and treat as soon as possible. Test your knowledge about the new blood biomarker used to test for brain injury and learn about health natural treatment options.

1. True or False. Both the glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase L1 (UCH-L1) blood biomarkers are detectible within one hour of brain injury.

A. True
B. False

2. Which blood biomarker increases the most quickly immediately following brain injury?

C. A and B increase at equivalent rates

3. According to study findings, the GFAP blood biomarker consistently detects which of the following features across seven days?

A. CT lesions
B. Mild to moderate traumatic brain injury (TBI)
C. Need for neurosurgical intervention
D. All of the above


4. True or False. GFAP is able to detect mild TBI and CT lesions within one hour of injury.

A. True
B. False


5. After peaking postinjury, GFAP declines over _____ hours while UCH-L1 declines over _____ hours.

A. 48;72
B. 60;60
C. 72;48


If you play contact sports you are more vulnerable to concussions and lasting brain damage if you don't take the time to recover.

Answer Key:

1. A. True - According to study findings cited in a literature review published online in Neurology Reviews, “[b]oth GFAP and UCH-L1 were detectable within one hour of injury.”

2. B. UCH-L1 - UCH-L1 blood biomarker “performed best in the early post injury period” and rose more rapidly than GFAP immediately following brain injury.

3. D. All of the above - “GFAP performed consistently in detecting mild to moderate TBI, CT lesions, and the need for neurosurgical interventions across seven days.”

4. A. True -GFAP does not rise as quickly as UCH-L1 but “‘it performs well for detecting mild TBI and CT lesions within one hour of injury

5. C. 72;48 - GFAP peaked at 20 hours postinjury and slowly declined over 72 hours. UCH-L1 rose rapidly and peaked at eight hours post injury, then declined rapidly over 48 hours.”
