Valtari Bio is developing a blood test to aid in the rapid triage of suspected stroke patients. Our ReST™ (Rapid evaluation Stroke Triage) test will help clinicians with or without stroke expertise make a confident initial stroke versus no stroke (e.g. complicated migraine, bell’s palsy, vertigo, dizziness, etc.) determination in ten minutes or less.


Unmet Clinical Need

Physicians need a rapid and confident method, from the moment a suspected stroke patient hits the door, for making an initial unbiased diagnosis of stroke versus no stroke. The current clinical standard is based solely on a clinician’s assessment of symptoms and rudimentary stroke scale tools. There is no simple, immediate, and unbiased way to diagnose stroke.

“If we are thinking like a clinician, then any given patient with any alteration in mental status or neurological exam COULD be a stroke. The level of SUSPICION in a clinician’s mind drives the diagnostic workup. The patients at HIGH suspicion are going to get the most workup, and Valtari Bio’s test will AFFIRM their thinking and drive fast treatment. For the patients who are at lower suspicion – Valtari Bio’s test is a safety net to CATCH the possible misses and drive suspicion and subsequent workup. We need this tool to significantly augment our overall clinical acumen for ruling in and ruling out suspected stroke.”

In emergency settings, 40% of non-strokes are misdiagnosed as stroke and 20% of strokes are missed

Current stroke scale methods for rapid and initial diagnosis are lacking
