摘　　要：目的了解湖南省二级以上医院凝血试验的检测质量及不同室间质量评价(EQA)方式间结果的差异,为进一步规范临床实验室管理和提高凝血试验检验质量提供依据。方法采用与常规EQA相同批号的质控品用现场测试EQA的方式,收集22家实验室的凝血试验检测结果,并对结果进行分析和评价。结果22家实验室四项合格率依次为PT-s(79.1%)、APTT(75.5%)、FIB(71.6%)、PT-I NR(69.1%),对异常水平质控物的检测PT-s、PT-I NR两项合格率明显偏低(27.3%、36.4%)。经χ2检验参加常规EQA活动的实验室现场测试EQA与常规EQA间各项目合格率差异无统计学意义(P>0.05),未参加常规EQA活动的实验室与参加常规EQA活动的实验室间现场测试各项目合格率PT-I NR、FIB差异有统计学意义(P<0.01),其他差异无统计学意义。结论应加强临床对凝血试验在保证医疗质量和医疗安全中的认识,促进实验室操作的标准化,加大对未参加常规EQA活动的实验室的质量监控,以提高检验质量。Objective To investigate testing quality of coagulation tests in laboratories of hospitals above secondclass in Hunan Province, to compare the difference between the results of different external quality assessment （EQA） methods, and to provide the evidence for further standardizing the clinical laboratory management and improving the quality of coagulation tests. Methods Using quality control serums which have the same batch number with normal EOA and site testing EQA method, we analyzed and evaluated coagulation tests results of 22 laboratories. Results The qualified rates of PT- s, APTT, FIB, and PT - INR of 22 laboratories were 79.1%, 75.5%, 71.6%, and 69.1% respectively. The qualified rates of abnormal quality control serums testing PT-s and PT- INR were significantly low （27.3 %, 36.4% ）. No statistically signifi- cant difference was found in the qualified rates of site testing EQA and normal EQA among the laboratories which took the qual- ified rates of site testing EQA and normal EQA by using X2 testing （P〉0.05）. The difference of the qualified rates of PT- INR and FIB between laboratories which did not take part in normal EQA and laboratories which took part in normal EQA showed statistical significance in X2 testing （P〈 0.01）, but no statistically significant difference was found in the qualified rates of oth- er items. Conclusions The recognition of blood coagulation tests in ensuring medical quality and medical safety shoulcl be strengthened in clinic. The standardization of laboratory operations should be promoted. The quality control for laboratories which do not take part in EQA should be enhanced for a higher testing quality.
