Blood test could unlock stroke treatment for thousands
NCT ID NCT03364296
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether measuring two proteins in the blood (GST-π and PRDX1) can accurately determine if a stroke occurred within the last 4.5 hours. That time window is critical because it determines if patients can receive clot-busting medication. Researchers enrolled 935 adults with stroke symptoms to test this approach. If it works, it could help treat people who wake up with a stroke or don't know exactly when symptoms started.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could give doctors a simple blood test to quickly determine when a stroke began, allowing more patients to receive timely clot-busting treatment.
What could go wrong
This is an early diagnostic study, not a treatment trial. The blood markers may not be accurate enough in real-world settings, and results may not change current practice.
