Different brand automatic instrument of coagulation test results contrast analysis / 中国医学装备

ABSTRACT

Objective: Based on the same clinical laboratory automatic blood coagulation analyzer method comparison of different brands. Discuss different between blood coagulation analyzer test results are comparable or check whether the deviation of the results in the permitted range. Method:collecting 112 cases of fresh plasma specimens, using ACL ADVANCE and Sysmex CA7000 two kinds of blood coagulation analyzer, respectively prothrombin time (PT), activated partial prothrombin time (APTT), thrombin time (TT) and fibrinogen (FIB), and compare the results, to medical decision level of judging system error detection system for clinical result, and calculate the two blood coagulation instrument testing results of the correlation coefficient and linear regression equation. Results:the ACL ADVANCE and Sysmex CA7000 blood coagulation analyzer test of PT, APTT, TT and FIB result comparison, there were no statistically significant difference (t=0.974, t=0.649, t=0.765, t=1.163;P>0.05), the correlation coefficient respectively;Medical decision level of system error were less than half the total margin of error. Conclusion:to the ACL ADVANCE as standard test system, Sysmex CA7000 determination results have clinical acceptability, two blood coagulation test results with good correlation. Should be conducted on a regular basis in the same laboratory coagulation analyzer compares different experiments, to ensure the comparability of the same in the laboratory test results.
