摘要
目的研究不同因素对凝血四项测定结果的影响,探讨优良方法的临床适用性。方法选择2012年10月于本院健康体检40例的血液标本,按照不同的抗凝比例和不同的放置时间测定PT、APTT、TT、FIB,分析比较各组测定的差异。结果抽血量在1.4mL(7∶1)、1.6mL(8∶1)和2.0mL(10∶1)时,与标准1.8mL(9∶1)测定的PT、APTT、FIB、TT值比较,差异均有统计学意义(P<0.05)。室温下放置4、8h和24hPT、APTT、FIB、TT值测定结果与即刻测定结果比较,差异也有统计学意义(P<0.05)。结论严格遵守标本采集和检测规范对测定数据的准确度有很大的意义,医务人员应认真掌握规范操作,为临床提供有效的指导数据。
Objective To study the effect of different factors on blood clotting measurement results. Methods Select the blood samples of 40 healthy patients at the hospital in October 2012, according to the proportion of different anticoagulant and different placement of the time to determine prothromhin time and activated partial thromhoplastin time,thromhin time,fihrinogen,analysis and comparison of the measured differences.Results Blood samples of 1.4mL （7 ： 1）, 1,6mL （8 ： 1）,and 2.0 mL（10 ： 1）,comparing with the standard 1.SmL （9 ： 1）,the determination of the PT, APTT, FIB, tt value had statistically significant （P 〈0.05）.Room temperature for 4 h,Sh and 24h PT, APTT, FIB, TT value measurement results comparing with instantly measurement results,the difference was also statistically significant （P 〈 0.05）. Conclusion Strict compliance with specimen collection and testing specifications is of great significance for the accuracy of the measured data,the medical staff to provide effective guidance for clinical data seriously grasp standardize operations.
