Soon, quicker and more precise way to diagnose stroke
In an attempt to prevent deaths from stroke, scientists are creating a new blood test that could quickly and more accurately confirm whether someone is having a stroke and what kind.
Steven A. Soper and colleagues note that strokes have two possible causes.
In ischemic stroke, a clot stops blood flow in a part of the brain. In hemorrhagic stroke, a blood vessel in the brain ruptures.
Both can lead to similar symptoms, such as numbness on one side of the body, sudden weakness and headache.
Current diagnostic tests can't tell between these two types. But treatment, ideally within three hours of onset, depends on the kind of stroke a person is having.
Soper's collaborator, Alison Baird, who is at SUNY Downstate Stroke Center, found clues — or biomarkers — in the blood that can suggest the stroke type and assist in determining the course of proper treatment.
Soper's team sought a way to detect those clues quickly.
They built a device that can process whole blood and isolate genetic material for two potential stroke biomarkers within minutes.
Keeping in mind that identifying more biomarkers could aid in diagnosis, they designed their device so it can analyze a total of four biomarkers at the same time.
The report appears in the ACS journal Analytical Chemistry.
