Abstract: The present invention relates to methods for the diagnosis and evaluation of stroke and stroke sub-type. A variety of bio-markers are disclosed for assembling a panel for such diagnosis and evaluation. Methods are disclosed for selecting markers and correlating their combined levels with a clinical outcome of interest. In various aspects: the invention provides methods for early detection and differentiation of stroke subtypes, for determining the prognosis of a patient presenting with stroke symptoms, and identifying a patient at risk for hemorrhagic transformation after thrombolyic therapy. Methods are disclosed that provide rapid, sensitive and specific assays to greatly increase the number of patients that can receive beneficial stroke treatment and therapy, and reduce the costs associated with incorrect stroke diagnosis.
