West Midlands Ambulance study to trial lateral flow test for strokes

West Midlands Ambulance Service is undertaking new research aimed at designing a lateral flow test which can quickly tell whether someone is having a stroke.

Diagnosing a stroke in the pre-hospital setting is difficult with currently over half of patients seen with suspected symptoms having a final diagnosis which is not a stroke.

Working alongside University of Birmingham and University Hospitals Birmingham, WMAS is undertaking the GHOST (Golden HOur for STroke) study to try and create an LFT test which will use saliva and subsequently help to speed up access to brain-saving treating like thrombectomy, saving more patients and helping ambulance crews avoid longer journeys to specialised stroke centres when they are not required.

The trial, which is being funded by the Stroke Association and began in August, is looking to recruit 200 patients during the next two years, with results expected to be published by the end of the 2026.

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.

“It is really important that people still use the FAST test initially and still call 999 immediately if they believe there any symptoms of a stroke.

“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.”
