Study Information for: "Biomarkers for Acute Stroke Etiology (BASE)" - Be Involved

What we are studying

Despite advances in medical care, the cause of 30% of strokes remains unknown. The purpose of this research study is to collect blood samples that can be stored and later analyzed to find information that might lead to new tests or treatments for acute strokes. The use of the biomarkers (blood components) within the blood samples may allow doctors to discover the cause of strokes, and help to determine the best course of treatment.
