filexlib. The monitoring device measures the time it takes an individual’s blood to clot. A drop of blood is obtained by a finger-stick using a lancet. The drop of blood is placed on a test strip and analyzed by the device. The device displays both the PT and calculated international normalized ratio (INR).
Approximately 70% of hospitals participating in the series of prothrombin time proficiency assessment trials organized from the National (U.K.) Reference Laboratory for Anticoagulant Reagents and Control and continue to use a manual technique routinely. The remainder employ a large variety of different types of automated procedure.

PT is measured in seconds. Most of the time, results are given as what is called INR (international normalized ratio). If you are not taking blood thinning medicines, such as warfarin, the normal range for your PT results is: 11 to 13.5 seconds. INR of 0.8 to 1.1. If you are taking warfarin to prevent blood clots, your provider will most likely
The prothrombin time of a normal plasma is 22 seconds (= 100% Quick). The ISI of the thromboplastin used is 0.93. Substituting this value in the formula gives the following INR: This signifies a coagulation time that is 2.7 times longer than the standard. The longer the patient’s coagulation time, the higher the INR. Hirsh et al. (2003). Components. Component Test Code*. Component Chart Name. LOINC. 0030220.

Testing time is patient’s actual Prothrombin Time (PT). When testing is complete, the meter beeps once and the results (INR and PT seconds) appear on the screen. Record the results. Remove the test strip and properly dispose along with the sample transfer tube and lancet. Turn off the meter by holding the power button down.
