PROTHROMBIN TIME (200. Rs./-)
PROTHROMBIN TIME (200. Rs./-)
The International Normalized Ratio (INR) will be routinely reported in addition to the Prothrombin Time in seconds. The reagents, and therefore the reference range in seconds, differ among the various UC affiliated hospitals. However, the INR adjusts for the inherent variability of tissue thromboplastins employed in the assay. When the prothrombin time is just above the upper limit of the normal range, calculation of the INR can result in a normal INR. This reflects the rounding of decimals utilized in the INR calculation. The INR is the parameter of choice in monitoring the adequacy of warfarin anti-coagulation, and should in theory remain stable. The appropriate therapeutic range will vary with the disease and treatment intensity desired. Some Prothrombin Time reagents can neutralizes heparin up to 2 U/mL. Hence in regard to samples drawn through heparinized lines: (i) the PT reagent neutralizes low levels of heparin and (ii) additional heparin neutralization can cause a reduction in coagulation factor levels. For these reasons, heparin neutralization is not recommended for PT measurements
