Conclusions: The current study provides further evidence that PoCT is an acceptable alternative to pathology laboratory tests in general practice. The Bland Altman method is a useful and flexible tool for evaluating chords. In future comparative method studies, approval limits should be reported to help clinicians manage patients. Methods: The results of the INR pathology were collected by several pathology laboratories and CoaguChek S PoCT devices over a period of 6 months. The agreement was evaluated both on the basis of a clinically relevant agreement and on the basis of the Bland Altman method. Results: The analysis is based on 1664 double measurements performed on 417 patients from 26 general practices across Australia. The share of dual measures corresponding to the expanded and narrow compliance criteria was 91% and 89% respectively. The average difference in results and agree limits at 95% depended on the average NSN result: average difference – -0.30 – 0.08 x average; 95% contract limits – -0.30 – 0.08 x average – 0.77. Objectives: to assess the level of correspondence between the results of the International Standardized Report (INR) of pathology laboratories and the one-off care tests (POCs) used in general practice.
