VIDAS® TBI (GFAP, UCH-L1)
How do you know if a CT scan is needed for mTBI?

VIDAS TBI quickly and accurately rules out intracranial lesions, enabling confident decisions and efficient triage for patients suspected of having mild traumatic brain injury (mTBI).

VIDAS TBI

Find out if your patient truly needs a head CT scan in ⁓39 minutes.*

This groundbreaking assay uses blood-based brain biomarkers to predict absence of intracranial lesions in mTBI patients and objectively assess the need for CT imaging.

  • Comprehensive: Safely rules out traumatic intracranial lesions and hemorrhage through the evaluation of two distinct brain biomarkers (GFAP and UCH-L1) at the same time.
  • High sensitivity (96.7%); High negative predictive value (99.5%): Accurate results that aid in clinical decision-making for CT scans and potentially reduce unnecessary radiation exposure.1
  • Wide-ranging test: Approved for patients 18 and over, with a large testing window of up to 12 hours after injury.1

⁓2.5 million
people are diagnosed with TBI every year, yet 80-90% have CT scans that do not reveal intracranial lesions.3

    Blood-based Brain Biomarkers

    This test detects the blood-based biomarkers GFAP and UCH-L1, which rapidly enter the blood stream following brain injury. The quick identification of these markers can aid clinicians in making informed clinical decisions related to patient care and resource management.

    High Negative Predictive Value

    Negative interpretation of VIDAS TBI is associated with the absence of acute lesions on a head CT scan, which enables clinicians to reduce unnecessary imaging, radiation exposure, and may potentially increase patient throughput.4,5
