Effects of Different Preservation Time of Clinical Qualified Inspection Samples on the Detection Results of Renal Function Indicators and Blood Sugar

目的探讨临床送检合格标本不同保存时间对肾功能指标及血糖检测结果的影响。方法选择我院2015年2月至2016年12月800例临床送检合格标本,分别在即时、6 h、24 h检测PFG、Cr、BUN水平,比较不同保存时间各指标检测结果的差异。结果临床送检合格标本在即时、6 h及24 h的PFG检测值依次降低,两两t检验显示差异有统计学意义(P<0.05);Cr、BUN检测值有所上升,但差异无统计学意义(P>0.05)。结论临床送检合格标本的PFG检测结果随保存时间的延长而明显降低,不适宜进行重复性检验;Cr、BUN检测结果在短时间内随保存时间的延长变化不明显,可为临床提供肾功能指标的复检服务。

Objective To explore the effects of different preservation time of clinical qualified inspection samples on the detection results of renal function indicators and blood sugar. Methods 800 clinical qualified inspection samples in our hospital from February 2015 to December 2016 were selected. The levels ofPFG, Cr and BUN of all samples were detected in real time, 6 h and 24 h respectively, and the differences of the detection results of different preservation time were compared. Results The detection value of PFG in real time, 6 h and 24 h decreased successively, and t-test showed that the differences were statistically significant （P〈0.05）. The detection value of Cr and BUN increased slightly, but the differences were not statistically significant （P〉0.05）. Conclusions The detection value of PFG of clinical qualified inspection sample decreases along with the lengthening of preservation time, which suggests that repetition test of PFG is not suitable. The detection value of Cr and BUN have no significant change with the prolongation of preservation time in a short time, which suggests that review service of renal function indicators can be provided for clinic.
