I wonder if I am unique with the difference between the fingerprick- test on my CoaguChek XS or on a machine at a hospital and the bloodtest in the vein at the hospitallab? My difference is an INR of 0,8 - 1.2 if I take the two tests within around 3 hours.
There is even a small discrepence (0,1 - 0,4). Otherwise the difference is THE SAME.
This must of course be very important that the patient knows but also the Doctor. Perhaps it only has to do with Lupus Anticoagulant but I am not sure.
I think of all of you out there who wants to selftest and trust what you hear and in fact does not know if the value is reliable. I do not mean the Roche-Machine which you can trust I am sure, but if the INR is to be trusted if it has been done via fingerprint or in the vein. I am most interested to know.
