The INR can not be ordered separately. INR is a part of the
Prothrombin time result INR is obtained by dividing the
patient's protime result by the geometric mean of the normal range raised to the exponential
value of the international sensitivity index (ISI). The ISI value is assigned by
the manufacturer for the type of thromboplastin reagent and instrument that is
used in the laboratory for the assay. INR values are essential for following the
current recommended therapeutic ranges for patients who are on oral
anti-coagulant therapy. INR = 2 to 3 for most patients and for patients with
mechanical prosthetic heart valves: INR = 2.5 to 3.5. |
