摘　　要：目的分析不同质量血液样本对血凝指标的影响,完善分析过程之外质量控制。方法对北方学院附属第三医院门诊或住院治疗患者原检测样本存在问题的34例样本进行重新采血,并重新检测新样本的血凝4项,包括活化部分凝血活酶时间(APTT)、血浆凝血酶原时间(PT),凝血酶时间(TT),纤维蛋白原(Fib)。结果原检测样本存在问题的因素包括样本量过少<2ml,样本存放时间过长>4h,采血部位为输液同侧,待检测样本含有凝块。与重新采血后合格样本的检测结果相比,APTT、PT、TT及Fib血凝4项均存在明显差异(P<0.05)。结论血液标本质量对血凝指标检测结果有直接影响,是分析过程之外质量控制的重要环节,为保证血凝检测结果的准确度及可靠性提高了先决条件。Objective To observe the effect of different quality blood sample coagulation test results. To perfect the qual ity control except in analysis period. Methods Totally 34 disqualification blood samples that were belonged to outpa tients or inpatients our hospital were recollected and activated partial thromboplastin time （ APTT）, prothrombin time （PT）, thrombin timr（TT） and fibrinogen （Fib）were retected. Results The disqualification factors were littlt capacity （ 〈 2ml） ,long time stored, transfusion homonymy blood collected, blood clot containe in old blood samples. The results of AtrI3,PT, TT and Fib in disqualification blood samples were difference compared with in qualification blood sam pies. Conclusion The quality of blood sample has dirct effect for the test results. Therefore, blood sample is an impor tant link of except in analysis period qulity control and the prereqoisite of accurate, reliable test results.
