Hi Noyolk,
I've been asking about instruction because speaking from experience INR testing is serious stuff and some patients need a certain level of comfort gained from an instructor.
Finger sticking and applying the blood isn't difficult. The doer just needs to feel comfortable, that's all.
Costs are different in our two countries so I can't comment.
We've always had excellent results with my XS, always.
