Hi Paul
I'm in UK too, as you can probably guess from my profile name
I have been self-testing since a few weeks after my AVR surgery in 2014,buying my own meter and then getting the test strips on prescription. If you experience any resistance to support from either your GP or anti-coagulation clinic, refer them to the
report by the National Institute of Health and Care Excellence, which by coincidence was published the same month I had my surgery. They set "best practice" standards for the NHS and came out strongly in favour of the CoaguCheck XS. Weekly self testing has been shown to have a massive benefit, both for us as patients and the NHS in reduced costs - it really is a no brainer.
If useful, I prepared a note to talk to my doc about doing this -
click here for a copy - which summarises some of the key points from the NICE report, both in "medical speak" and plain English. I turned out not to need this note - both my GP and clinic are very supportive. I now do my own test weekly, all the time, and email an INR reading whenever the clinic wants, which is mostly every 6 weeks, or more frequently if they wish, and I attend the clinic once every 6 months for a lab test to check my meter is still within the expected range. By managing my own Inr I have been 100% in range for the last year or more.
I am happy to chat more if needed - feel free to message me. It is soooo great not to be tied to attending the clinics too - I take my meter on holiday of course, as different diets usually mean I need to adjust my dose. I don't actually tell my clinic when I do adjust the warfarin dose, unless I don't understand why or the reading change is dramatic, and then I give them a call or go in. I am an insulin dependent diabetic, and so am used to adjusting insulin doses after doing a finger-prick test, and although adjusting warfarin is a bit trickier because of the time lag in seeing the effect of the change, because you have your own meter you can make a small change, usually temporary I find, and see the effect by testing more frequently, eg every three days, until things settle down. You are the one with most to lose if out of range, and I like to take responsibility for my own health.
One final point - I much prefer a finger-prick test to a blood draw - my veins nearly collapsed when I had my surgery through frequent tests, and they ended up taking blood from my foot!
It seems I can only link to one document per post, so I will add another post with a link to the full NICE report.
