Microfluidic Chip May Be Able To Quickly Tell Whether Someone Has TBI From Finger-Prick Blood Sample, Researchers Say

Physics World (UK) (2/20) reported “researchers in the UK claim to have developed a microfluidic chip that can rapidly tell whether someone has suffered a traumatic brain injury from a finger-prick blood sample.” According to the article, “the optofluidic device detects a biomarker linked to brain injury, based on the way that it scatters light.” The researchers “claim that by testing for elevated N-acetylasparate levels, they were able to identify patients with traumatic brain injury with an accuracy of almost 99% immediately after injury, and around 91% at eight and 48 hours after injury.” The findings were published in Nature Biomechanical Engineering.
