The user-friendly design has audio, color, and light cues that can signal the operator to critical results. 3 Its durable construction allows for fast-paced environments and is built with materials that can resist damage. The cartridge is then inserted into the handheld instrument.Ībbott's rapid i-STAT TBI Plasma test includes a high-resolution color touchscreen, enabling simple and intuitive navigation, an easy-to-replace rechargeable battery, a high-resolution camera that captures 2D barcodes with picture ID, and an easy-grip ergonomic designed that makes use balanced, comfortable, and secure. Following a blood sample drawn from a patient’s arm, plasma is extracted with a centrifuge and applied to the test’s cartridge. CT scans, often used to diagnose concussion, can then be ruled out if a patient has a negative test result. 2 The test measures specific proteins present in the blood after a TBI and provides results in as little as 15 minutes after plasma is placed in the test cartridge. In January 2021, the FDA cleared Abbott's rapid i-STAT TBI Plasma test, the first rapid handheld TBI blood test, to assist clinicians in assessing patients with suspected mild TBIs, including concussions. Results are complete in as little as 18 minutes, and are then shared with the provider for further evaluation. In a statement, 1 McQuiston noted that hits to the head are often minimized or ignored and that some "wonder if a visit to the doctor or emergency room for a possible concussion will provide them with meaningful answers or care."Ībbott's Alinity i TBI lab test evaluates patients who are 18 years of age or older that present suspected mild TBI within 12 hours of injury (scoring between 13 and 15 on the Glasgow Coma Scale), determining whether they are candidates for a CT scan. A blood sample is drawn from the arm and then sent to the lab for preperation to be run on the Alinity i instrument. This is only the beginning of advancements in concussion testing as we continue to research future indications for both adults and children.” This lab test for concussion will be a game changer for concussion assessment in hospitals, giving clinicians an objective tool to quickly assess a possible brain injury, triage patients, and reduce the number of unnecessary CT scans-giving people who test negative peace of mind. Notably, clinicians can receive a reliable result from the test in 18 minutes, with a 96.7% sensitivity and 99.4% negative predictive value.īeth McQuiston, MD, medical director in Abbott's diagnostics business, told NeurologyLive ®, “We are seeing the beginning of the future in how concussions are evaluated. The test measures 2 biomarkers in the blood plasma and serum, ubiquitin C-terminal hydrolase L1 (UCH-L1) and glial fibrillary acidic protein (GFAP), both of which are tightly correlated to brain injury. The test will be available in hospitals to quickly assist clinicians in assessing patients with mild TBIs, known as concussions, in an objective way and help develop the next steps of care for patients. According to news from Abbott, the FDA cleared its Alinity i laboratory traumatic brain injury (TBI) blood test, the first commercially available test of its kind.
