Yes, the 2.2 needs to be addressed; after consulting with the warfarin management program here I increased my dosage for 1 day by 2 mg and will recheck earlier than normal to see if my INR is back in range. I suspect it's just an aberration; my INR has been extremely stable at 2.7 to 2.8 for the past month, taking 8 mg of warfarin per day. The fact that those numbers are fairly close to the bottom of my range is actually why I decided this was a good time to check my home test results against the lab, in case my meter was reading higher as some report the INRatio does. For the record, the 2.2 was my INRatio score, with the lab result coming in at 2.3, so I'm just a hair below range. At any rate, between the extra warfarin dose and the wine festival I am attending for the next 3 days, I'm pretty sure I'll be back in range by Monday!
By the way, Marc, like you I did my home test immediately after getting the blood drawn in the lab; probably about 15 minutes later, just long enough to drive straight home and get my meter out.
As for worrying about the kale in the soup, I don't. I eat a lot of greens, although I do kind of avoid kale for the most part, just because it has so much more vit k than most other foods. I probably did take in more vit k than normal, though, and that intake was 4 days prior to testing, so it likely would have made a difference. I just have to remember that any increase in vit k intake needs to be balanced by increased intake of wine and single malt scotch
You can never be too careful....
