Thanks for all the responses. I have started a spreadsheet (goggle) and am populating this each time I get blood results. Like others have mentioned I think it is important to document to look for any trends and to demonstrate I can competently manage my warfarin intake.As others have posted, I too keep a spreadsheet with the basic info -- test date, results, dosing changes (if any) and notes that I think may be relevant at the time. Though I have been home testing only about a year, it has been helpful already in showing me where I have been at different times and useful as a guide to new doses as time goes on and as repeated situations arise (like having to take an antibiotic). I have not used any apps, though I have referred to the dosing algorithms (links found on this site), but, as time has gone by, I tend to know what I need to do to get in range.
Would anyone please post this kind of spreadsheet, so I can get an idea of how it looks? I’ve seen one or two on this site, but not with any comments, & am curious how I could set it up. I’m not as excel-savvy as I could be...I created a simple spreadsheet (microsoft Excel) with colums for: date, INR, dose, comments.
