Would anyone have any idea why, after months of being at a stable INR of around 2.5 to 2.8, my INR has dropped to 2.1, despite no real change of diet etc.
I test myself weekly, only going to the surgery for testing every couple of months as directed, tested last week at 2.4 and this week at 2.1.
I spoke to my GP yesterday but he didn't seem concerned as long as I didn't drop below 2. Of course I understand the recommended range is between 2 and 3, but taken into account all that has been written and said about inconsistencies I prefer to be at the higher end of the scale.
Any thoughts/comments gratefully received.
