Analysis of emergency sample testing time of the VITROS XT 3400 biochemical testing system

目的:分析VITROS XT 3400生化检测系统急诊样本检测时间,评估其检测方法。方法:回顾性分析2020年8月至2022年7月复旦大学附属中山医院急诊检验科所有包含白蛋白(Alb)、总蛋白(TP)、丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、肌酐(Cr)、血尿素氮(BUN)、钙(Ca)和葡萄糖(Glu)项目的样本,计算复合干片项目配对率。采集2022年6月20—26日复旦大学附属中山医院急诊科635例患者血清样本,分别在VITROS XT 3400(复合干片)与VITROS 4600(普通干片)仪器上进行检测,比较2组样本检测时间和低、高峰时间段的样本检测时间差异,及2台仪器试剂更换与日保养时间。结果:3对复合干片项目(Alb-TP、AST-ALT、Cr-BUN)配对率均>99%;VITROS XT 3400组样本检测时间低于VITROS 4600组[(945±477)s比(1101±567)s,t=20.378,P<0.001];低、高峰时段VITROS XT 3400组样本检测时间均低于VITROS 4600组[低峰时段(n=322):(857±567)s比(905±528)s,t=13.102,P<0.001;高峰时段(n=313):(1035±400)s比(1303±492)s,t=21.876,P<0.001];VITROS XT 3400组试剂更换时间低于VITROS 4600组[(690±127)s比(869±152)s,t=11.470,P<0.001];VITROS XT 3400组日保养时间与VITROS 4600组比较,差异无统计学意义[(1771±123)s比(1765±95)s,t=0.238,P=0.834]。结论:VITROS XT 3400(复合干片)较VITROS 4600(普通干片)对急诊样本的检测速度快,能更好地缓解检测压力。

Objective To analyze the emergency sample testing time of VITROS XT 3400 biochemical testing system and evaluate its testing method.Method Retrospective analysis was conducted on all specimens from the emergency laboratory department of our hospital from August 2020 to July 2022,including albumin(Alb),total protein(TP),aspartate amino transferase(AST),alanine aminotransferase(ALT),creatinine(Cr),blood Urea Nitrogen(BUN),calcium(Ca)and glucose(Glu)to calculate the utilization rate of composite dry slide projects.A total of 635 serum samples were collected from emergency patients in our hospital from June 20 to 26,2022,and the difference in sample testing time was compared between VITROS XT 3400(composite dry tablets)group and VITROS 4600(ordinary dry tablets)group during low and peak periods.The difference in replacement reagent and daily maintenance time was also compared between the two groups.Result The pairing rates of three projects(Alb-TP,AST-ALT,Cr-BUN)are all over 99%.The detection time of the VITROS XT 3400 group samples was significantly shorter than that of the VITROS 4600 group[(945±477)s compared to(1101±567)s,t=20.378,P<0.001].The detection time of the VITROS XT 3400 group samples during high and low peak periods was significantly shorter than that of the VITROS 4600 group[low peak period(n=322):(857±567)s compared to(905±528)s,t=13.102,P<0.001;peak period(n=313):(1035±400)s compared to(1303±492)s,t=21.876,P<0.001],The reagent replacement time of the VITROS XT 3400 group was significantly shorter than that of the VITROS 4600 group[(690±127)s vs(869±152)s,t=11.470,P<0.001].There was no statistically significant difference in daily maintenance time between the VITROS XT 3400 group and the VITROS 4600 group[(1771±123)s vs(1765±95)s,t=0.238,P=0.834].Conclusion XT 3400 has faster detection speed when using the composite dry slides,which can better alleviate the detection pressure during peak hours.
