目的:探讨有效控制街头采血丙氨酸氨基转移酶(ALT)报废率。方法:对492名街头无偿献血者经干式生化分析仪初筛合格(ALT<40U/L)而回站内经大型全自动生化分析仪复检不合格(ALT≥40U/L)的血液情况进行分析,寻找规律;同时,随机抽取20名无偿献血者血样经干式生化分析仪和全自动生化分析仪准确检测,对数据进行直线相关与直线回归的统计学分析。结果:492名干式生化分析仪初筛合格而全自动生化分析仪复检不合格情况有规律性;干式生化分析仪与全自动生化分析仪直线相关性良好r=0.994 0,直线回归方程为y=0.485 4+0.976 9x,当全自动生化分析仪x取值40时,个体干式生化分析仪y值的95%容许区间为:34.57~44.55U/L。结论:干式生化分析仪初筛限值ALT≥33U/L为不合格时,回站内全自动生化分析仪复检ALT≥40U/L的为零,可有效控制街头采血ALT报废率。
Objective: To explore the effective control of street ALT abortion rate. Methods: 492 street unpaid blood donors through the first round of qualified biochemical analyzer (ALT <40U / L) and back to the station by large automatic biochemical analyzer failed to retest (ALT> 40U / L) of the blood situation At the same time, 20 randomly selected blood samples from blood donors were detected by dry biochemical analyzer and automatic biochemical analyzer. The data were analyzed by linear correlation and linear regression. Results: 492 dry biochemical analyzer qualified and automatic biochemical analyzer re-examination failed regularity; dry biochemical analyzer and automatic biochemical analyzer good linear correlation r = 0.994 0, the linear regression equation For y = 0.485 4 + 0.976 9x, when the automatic biochemical analyzer x value of 40, the individual dry biochemical analyzer y value 95% allowable range: 34.57 ~ 44.55U / L. Conclusion: When ALT≥33U / L of primary biochemical analyzer is unqualified, ALT≥40U / L is zero for automatic biochemical analyzer back to the station, which can effectively control the ALT rejection rate of street blood collection.
