Scientists have developed a simple blood test that could diagnose within minutes whether or not a patient has suffered a stroke.
A stroke occurs when the brain is not getting enough oxygen, either form a clot or a burst blood vessel. In each type, if the wrong treatment is given it can be fatal to the patient.
In order to determine if the patient has suffered a stroke, doctors rely on brain scans but many have to wait for vital hours before they can get access to a scanner and fewer than a quarter receive a scan on the day they suffer their strokes.
