RESUMEN
Objective To evaluate accuracy and consistency of the coagulation convention that involves PT, INR, FIB, APTT on two coagulation analysators(ACL-9000 and ACL-200, Beckman-Coulter Corporation, US). Methods The repeatability test was used to assess the precision, the accuracy and consistency of the coagulation convention on two coagulation analysators were evaluated by comparison and analysis. Results The repeatability of related test results based on ACL-9000 coagulation analysator was better that CV value less than 5%, but the repeatability of abnormal specimens FIB based on ACL-200 was poor that CV value of 6.6%. Through comparing ACL-9000 analyzer, the test results of ACL- 200 coagulation analysator has good correlation with it, correlation coefficient ?﹥0.975. Conclusion In the condition of the excellent precision and stability, we can also find system errors existed in the analyzer on time by verificating. Through being adjusted and calibrated, the examination department can deliver the results of accuracy consistency.
