47M in Connecticut. I had an aortic valve replacement on 7/7 with an On-X mechanical valve and am trying to get set up for home INR testing.
My cardiologist and health system apparently don’t participate in home testing, so I’m not sure where to start.
Has anyone dealt with this? Did you go through insurance, another anticoagulation clinic, or directly through a home-testing company? Any advice, especially from anyone in CT, would be appreciated.
I checked my INR at 10:00 this morning and it was a bit high (3.6). So I cooked some broccoli and ate that. Later had a PB&J sandwich. Tested later around 5:00 and got a reading of 4.0 - what the heck? Why would that happen? I had a beer with dinner last night. Did the alcohol from the beer (low level alcohol) take that long to affect my INR? Total confusion.
I had an aortic valve replacement and have a mechanical valve. It ticks like a clock 🙂 I'm on warfarin for life.
I went from the yellow book to an Excel sheet, and then built an app for myself. Sharing it in case it helps someone here.
It logs INR results, doses, vitamin K, activity and health events, with reminders, an INR chart with your target range, and email/export to your clinic.
It doesn't calculate or suggest doses. It's a logbook, not a medical device.
No account, no ads, no tracking. Your data stays on your phone.
Most of it is free. There's an optional one-time £4.99 (no subscription) for extra charts and a PDF clinic report.
iPhone only for now, and not available in the EU. I'd love feedback from long-time warfarin folks on what would be useful.
