Patient Self Testing Makes Weekly Testing Possible

Evidence suggests that the benefits of home INR testing/monitoring are most likely more than a result of simply increased frequency of PT/INR testing that is made feasible by the use of testing devices in the home. Reasons that the use of these devices can lead to increased TTR include:

  • More information allows the patient to make adjustments more quickly.
  • More frequent testing also provides the ability to detect any drift in INR stability sooner, thus keeping INR within a set range.
  • Greater TTR is also probably a result of the fact that self testing allows the patient to evaluate how lifestyle events affect INR stability. This timely feedback may then allow the patient to modify lifestyle elements and improve INR stability.
  • Frequent INR results may increase physician comfort with targeting INR in the therapeutic range rather than under-anticoagulating as a strategy for minimizing dangerously high INR occurring during the usual 4- to 6-week interval between tests.
