The PT is usually measured in seconds and is compared to a normal range that reflects PT values in healthy individuals. Because the reagents used to perform the PT test vary from one laboratory to another and even within the same laboratory over time, the normal ranges also will fluctuate. ...
The 60 patient samples analyzed in this study had a large range of PTLab/INRLabvalues, from 12.6 s/1.0 to 115.4 s/14.1, with a mean of 33.9 s/3.3 and a median of 35.1 s/3.4. For reference, the diagnostic normal range of the laboratory PT/INR is 11.0 s/0.9 to...
Methods This study composed of 100 warfarin therapy patients and 20 coagulation normal subjects, showed that the difference between the POCT and clinical laboratory values increased with increasing INR and was exacerbated by the use of different thromboplastin reagents by the POCT and central lab. ...
Methods Prothrombin time(PT),international normalized ratio(INR),activated partial thromboplastin time(APTT) and fibrinogen(FIB) concentration of 56 patients in AP group and normal control(NC) group were detected by full automatic blood coagulation analyzer. 方法用全自动血凝分析仪,检测AP组和正常对照...
The procedure does not require manual PT testing, local international sensitivity index calibration, availability of thromboplastin IRPs or local mean normal prothrombin time. CONCLUSIONS: From the PT/INR Line, INR values for local PT results are easily obtained using an Excel spreadsheet from our ...

Examines indications of prothrombin time (PT), activated partial thromboplastin time (APTT) and international normalized ratio (INR) numerical values in different disease cases. Information about normal values of PT, APTT, INR; Indications of prolonged PT and APTT; Numerical values on deep vein throm...
Local verification and assignment of mean normal prothrombin time and International Sensitivity Index values across various instruments: recent experience ... Warfarin dosing relies on accurate measurements of international normalized ratio (INR), which is calculated from the prothrombin time (PT), Internat...

12. The Mean Normal Prothrombin Time [MNPT] is calculated from the geometric mean of at least 20 individual normal plasma PT values. 13. Do not use adult Reference ranges when commenting on or interpreting the results of clotting tests in the neonate. See section on Paediatric Reference Range...
