Summary

This study aims to create a rapid blood test that can tell if a stroke is caused by bleeding or a clot, using a protein called GFAP. Researchers will test this in 527 adults with suspected stroke at the hospital. The goal is to help doctors start the right treatment faster, especially before reaching the hospital.
