Analysis and treatment of abnormal results of Sysmex CA-1500 automated coagulation analyzer / 国际检验医学杂志

ABSTRACT

Objective To analyze the parametric errors during the use of Sysmex CA-1500 automated coagulation analyzer and their treatment measures .Methods Blood samples with test results showing “*”and without figure results were collected .Sysmex CA-1500 automated coagulation analyzer was employed to retest prothrombin time (PT ) ,activated partial thromboplastin time (APTT) and fibrinogen(FIB) .Results FIB ,PT and APTT were found abnormal in 226 cases(95 .77% ) ,5 cases(2 .12% ) and 5 cases(2 .12% ) ,respectively ,with FIB the mainly .ERR008 ,ERR004 ,ERR016 ,ERR002 ,ERR032 and ERR100 were found abnormal in 227 cases(76 .95% ) ,64 cases(21 .69% ) ,one case(0 .34% ) ,one case(0 .34% ) ,one case(0 .34% ) and one case(0 .34% ) ,respec-tively ,with ERR008 the mainly .Difference of no-error results between the initial and repeat test of PT and APTT showed no statis-tical significance(P>0 .05) ,while those of FIB demonstrated statistical significance (P<0 .01) .Conclusion Samples with paramet-ric errors during the use of Sysmex CA-1500 automated coagulation analyzer should be retested to promote the quality of blood co-agulation detection .
