There was a question from Jamie about CoaguChek. I had an aortic valve replacement in 1997 and have been using a CoaguChek XS for six years. I initially bought it because I was not happy with the phlebotomists at the local health centre; their hygiene was questionable, I didn't like sitting in a waiting room for about an hour, it was inconvenient and at the time I went a lot of cruises and I now spend the winters in St Lucia and tests are expensive. After some initial fumbling I get on extremely well. It is portable, accurate and if you can afford it (£400 or US$620) very convenient. I have learned a couple of things which may help: the hardest thing I found was to get a large enough drop of blood to get a reading within the allotted time and would use multple test strips. I put the lance on maximum and took ten minutes to stop the bleeding. Now I put the selected finger in a cup of hot water and get it right straight away. If you an afford it, I get the lances and test strips on the NHS, I would recommend it. It can also be used with pinpoint accuracy to reduce my INR for dental surgery, eye surgery and to remove skin cancers.
