Pocket-Sized clot test could change surgery prep

This study looked at whether a small, portable device called Hemochron Signature Elite can accurately measure blood clotting (INR) compared to standard lab tests. It included 24 adults who had stopped taking warfarin before surgery. The goal was to see if the device gives reliable results quickly, which could help doctors decide if it's safe to use a type of anesthesia called central neuraxial blockade.
