Prothrombin test is most common to use for monitoring in oral anticoagulant therapy Warfarin and related coumarins. The PT responds to reduction of three of the four vitamin K-dependent procoagulant clotting factors (II, VII, and X). This PT test gauges the time or period of reaction of Plasma to Thromboplastin and Ca++ that results to Fibrin Clot.
The INR value is calculated from the patient's coagulation time. However, the ISI value is included in the calculation. The manufacturer calculates the ISI value (International Sensitivity Index) by comparison to an international standard thromboplastin. This way, the different sensitivities of reagents available in the market are compensated.
Our result of INR 1.1 and PI% 90.9 is comparable and consistent with results of all other groups which ranges between 0.9 and 1.1 and it is also quiet comparable and consistent with the class mean result for INR and PI index.
6. Examine the ten results listed on page 4. These results were obtained when single quality control plasma (taken from the same bottle) was tested ten times. Are there any interesting features apparent with these results Do you think these results are acceptable
The mean INR value for the results is 3.07,two readings i.e 2.6 and 2.0 are quiet distant from the mean and comp
