Last Sept18, I had my sched for my testing of my PTPA(INR testing) and my results was not Good, 1.350 is very very low from my expected normal range (2.0-3.0). Every month I had this testing and with the last 3 months I didnt get in my normal level.
I thought the reason why it's because of my diet but I always monitored my VitK in take. I have so many question in my mind? I take Coumadin 5mg everyday in 3 years with normal level, for this 3months I got this problem, did it affect when the coumadin change from TORA brand(circle to oblong)? My doctor advice me to check again the INR within 2 weeks.
