Advice & TipsIf your Dr. (usually a Cardiologist) puts you on this following an episode of finding a clot, BE SURE TO GET THEM TO DO A PROTEIN C & S TEST for Hereditary blood clotting disorder. I DO have the Hypercoaguability disorder because blood clots killed a large number of folks in my mother's family. I'll be on it for the rest of my life. AND be careful of how much greens you eat, especially kale and spinach and if you are a traveler on airplanes or sit a long time, be sure to get up and walk around every 1 to 2 hours! The circulation in your legs is critical for this. Also, drinking cranberry juice can also affect your INR rate. So be careful with that as well.
