目的：评价Sysmex CA-1500全自动血凝仪PT-der法和Von-Clauss法测定血浆纤维蛋白原（Fib）的相关性和准确性。方法采用Sysmex CA-1500全自动血凝仪PT-der法和Von-Clauss法分别测定755例血液标本的血浆Fib浓度；高Fib浓度标本的稀释比例为1∶8、2∶7、3∶6、4∶5、5∶4、6∶3，以稀释比例为横坐标，以2种方法测得的Fib浓度为纵坐标，进行简单线性回归分析。结果 Fib：2．0～＜6．0 g/L时，Von-Clauss法检测Fib值高于PT-der法（P＜0．01）；Fib：＜2．0 g/L ，＞6．0 g/L时， PT-der法检测Fib值高于Von-Clauss法（P＜0．01）。PT-der法和Von-Clauss法检测的线性回归方程分别为：Y ＝4．5377 X＋1．5513（R2＝0．8973），Y＝7．7922X＋0．2900（R2＝0．9805）。结论 Von-Clauss法能较好地反映人体内具有凝血功能的Fib水平。

Objective To evaluate the relevance and accuracy of fibrinogen (Fib) detection by using PT-der assay and Von-Clauss assay on Sysmex CA-1500 Automated Coagulation Analyzer .Methods PT-der assay and Von-Clauss assay on Sysmex CA-1500 Automated Coagulation Analyzer were employed to detect the plasma Fib concentrations of 755 blood samples .The dilution ratios of samples with high Fib concentration were 1∶8 ,2∶7 ,3∶6 ,4∶5 ,5∶4 ,6∶3 ,respectively .The dilution ratios were served as the abscissa ,and the Fib concentrations measured by two methods as the ordinate ,a simple linear regression analysis was per-formed .Results When Fib concentration was in 2 .0- <6 .0 g/L ,the Fib value obtained by Von-Clauss assay was higher than that by PT-der assay(P<0 .01) .When Fib concentration was below 2 .0 g/L or above 6 .0 g/L ,the Fib value obtained by PT-der assay was higher than that by Von-Clauss assay(P<0 .01) .The linear regression equations of PT-der assay and Von-Clauss assay were Y=4 .537 7X+1 .551 3(R2 =0 .897 3) ,Y = 7 .792 2X+ 0 .290 0(R2 =0 .980 5) ,respectively .Conclusion Von-Clauss assay can better reflect the Fib level of human body which has a blood clotting function .
