Like most people I get my Warfarin level checked by a nurse every few weeks. Recently I purchased a Coagucheck XS device so that I could take in-between tests just to ensure that my levels were stable. However, I have found the Softclix lancing device supplied with the Coagucheck kit inadequate inasmuch as it consistently fails to puncture my finger deeply enough to obtain enough blood in the short time allowed (i.e. three minutes). As a result I often waste a testing strip. Conversely, my nurse uses a different type of lancing device - a single-use one - which always produces the correct amount of blood in the time allowed and I should like to know the make and grade of that lancing device so that I can use it too. FYI I live in Scotland and no Scottish health board supports self-testing for Warfarin, except Greater Glasgow & Clyde which only supports it for young people under eighteen. Therefore I have to buy all my strips from Roche and anything else required for the Coagucheck XS machine. But I am not too worried about that so long as everything works properly. So, all advice most gratefully received.
