Figure 2. Temporal Profile of Plasma Biomarkers in 48 Participants With mTBI Who Completed Sampling at Both <6 Hours and 7 Days.

Figure 2

Analyzing within subjects, comparing baseline (<6 hours) and 7 day testing, we observed significantly elevated levels of GFAP (A), UCH-L1 (B), and IL-6 at 6 hours. Conversely, NfL (C) exhibited an increase at 7 days. GFAP = glial fibrillary acidic protein; IL = interleukin; mTBI = mild traumatic brain injury; NfL = neurofilament light chain; UCH-L1 = ubiquitin carboxy-terminal hydrolase L1.
