Does a portable INR/PT monitor provide accurate measurements compared to clinical laboratory determinations in outpatients?
Portable INR/PT monitors provide accurate measurements comparable to clinical laboratories, facilitating rapid warfarin dose adjustments in outpatient settings.
White et al. (1994) conducted a review in Patients requiring INR/PT monitoring. Portable INR/PT monitor vs. Clinical laboratory determinations was evaluated on Measurements within 0.9 INR units of the corresponding laboratory value. A portable INR/PT monitor was accurate compared with clinical laboratory determinations, with approximately 85% of measurements within 0.9 INR units of the corresponding laboratory value.
