目的:研究血液筛查试管标本与血辫标本检测结果的符合情况,探讨血液保养液对检测结果的影响,确保检测结果的准确性。方法:对2014-05-2015-05无偿献血者67 436份标本用ELISA筛查出的HBsAg643例、抗-HCV 304例、抗-HIV 290例、抗-TP 270例反应性标本,与其血辫标本检测结果进行比较。结果:HBsAg、抗-HCV、抗-HIV、抗-TP试管标本与血辫标本符合率分别为63.58%、54.55%、58.73%、80.23%;试管标本与血辫检测平均值比较,t值分别为6.58、5.01、2.87、6.48,P<0.05;试管标本与血辫阳性率比较,χ2值分别为189.69、137.19、62.06、45.14,P<0.05。结论:血站血液筛查试管标本与血辫标本结果有差异,血液保养液对血辫有稀释作用,易造成弱反应性标本的漏检,应采取有效措施,提高检测结果的准确性,确保临床血液安全。
Objective: To study the coincidence of blood screening test specimens and blood bank test specimens, to explore the effect of blood maintenance liquid on test results and to ensure the accuracy of test results. Methods: A total of 67 436 samples of unpaid blood donors from May 2014 to May 2015 were enrolled in this study. There were 643 HBsAg-positive, 304 anti-HCV, 290 anti-HIV and 270 anti-TP reactive specimens, Specimen test results were compared. Results The coincidence rate of HBsAg, anti-HCV, anti-HIV and anti-TP test was 63.58%, 54.55%, 58.73% and 80.23% respectively. The mean values of t test 6.58,5.01,2.87,6.48, P <0.05; χ2 values were 189.69, 137.19, 62.06, 45.14, respectively, P <0.05. Conclusion: There is difference between the results of blood screening blood test and blood bank test. The blood maintenance fluid has a dilution effect on blood bank pigtail, which can easily lead to the missing test of weakly reactive specimens. Effective measures should be taken to improve the accuracy of testing results and ensure Clinical blood safety.
