When checking my INR this morning the error 5 came up on my metre so I had to recheck using another strip. My INR needs to be between 2 and 3. As this was the last strip I proceeded to test myself (1.9, so up the Warfarin to 5mg) and then changed the chip to ensure I was set for next week. Without the XS I’d be really stuck because I would have to go to hospital to get my INR checked. The kit cost £500 but it means I can check myself weekly and so monitor my INR range more closely and do have to go and wait at the hospital.
I’ve used the Coagucheck XS and its predecessor since having my aortic heart valve replaced in 2002 with a titanium one following a few heart attacks.
