The INRatio2 system required more repeat tests, thereby
requiring more test strips and more fingersticks, which are
associated with higher testing costs and more painful PT/
INR testing. The CoaguChek XS system was preferred to
the INRatio2 system 98 to 1 by patients in this study.
From a healthcare provider perspective, fewer repeat tests,
less patient discomfort and self-reported patient preference
should favor the CoaguChek XS system compared to the
INRatio2 system.
