A missed INR check isn't a missed appointment. It's three weeks of not knowing.
Warfarin has a narrow window. Drift low and you're risking a clot; drift high and you're risking a bleed. Diet, illness and a new prescription all move it, which is why the interval between checks matters as much as the checks themselves.
microINR reads from 3 μL at the point of care — or at the patient's kitchen table with a physician's prescription. Fewer reasons to skip, fewer weeks in the dark.
Requires a CLIA license, or a physician RX for home self-testing.
