Gene test could slash repeat stroke risk

This study looks at whether a simple genetic test can help doctors pick the right blood thinner for stroke patients. About 350 people who had a mild stroke or mini-stroke will be randomly assigned to either standard care or genetic testing. Those with a gene change that makes clopidogrel less effective will get a different medication. The goal is to see if this personalized approach reduces the chance of another stroke or heart problem over the next year.
