Ambulance study to trial lateral flow stroke test

The lateral flow test uses saliva to identify if someone is having a stroke

Ambulance crews across the West Midlands will take part in research to speed up identifying whether someone is having a stroke.

The West Midlands Ambulance Service Golden Hour for Stroke study will trial a lateral flow test that uses saliva to find stroke markers.

About 200 patients will be recruited to take part in the two-year experiment, with results expected to be published by the end of 2026.

Paramedics said the study would have no impact on patient care while it is being carried out.

The trial is being funded by the Stroke Association charity and ambulance crews will be working alongside University of Birmingham and University Hospitals Birmingham.

It is hoped it will fast-track access to brain-saving treatments like thrombectomy, and reduce journeys to specialised stroke centres when they are not required.

WMAS lead research paramedic, Josh Miller, said: “This is a major piece of research which could have a hugely positive impact on stroke care within the West Midlands.

“Ambulance crews who are taking part in the study will still conduct the "FAST" test themselves when they arrive on scene with a patient, before collecting a saliva sample if they believe there are possible signs of stroke.

"There is absolutely no impact to the patient care provided by us taking part in the research.”

The FAST test looks for stroke symptoms and stands for face weakness, arm weakness, speech problems and time to call 999.
