LJ-2000型粪便常规分析仪临床应用评价

The clinical application evaluation of LJ - 2000 conventional analyzer of feces

目的通过粪便常规分析仪测定与传统的人工镜检方法作比对，发现粪便常规分析仪能在检测标准化的同时消除人为因素造成的检测误差，使检测结果更加准确，而且避免交叉感染现象的发生。方法采取病人合格标本136例在粪便常规分析仪上检测，同时由经验丰富的检验人员通过镜检的方法得到检测结果，然后用统计学方法进行比较和判断：结果仪器进行标本检测后进行空白测定，图象中基本无异物，避免交叉污染的发生。在136份人工镜检的结果报告中阴性病例95份，阳性病例41份。而粪便常规分析仪检测结果为95例无异常，13例标拳发现红细胞，25例标本发现白细胞，2例标本发现酵母样茵，9例标本发现脂肪滴（脂肪球）。结论采集痛人标本的同一部位，仪器检测结果准确性等同于传统镜检结果、但粪便常规分析仪操作简便、标本处理检测过程标准化，降低人为误差，同对避免标本污染及交叉感染现象的发生，值得格隶推广使用，

Objective To make a comparimn between the determination by the conventional analyzer of feces and the manual micrnscopic examination in order to prove that the conventional analyzer of feces can help prevent cross - infection by eliminating human - induced detection errors and by imprnving on the accuracy of the results of detection. Methods Standard samples of 136 patients were collected and examined with the eonventional analyzer of feces while these samples were also detected through microscopic examination by experienced laboratory assis- tants. The results of examination using two different methods were compared and treated statistically. Results Blank determination was conduct-ed tollowing the instrumental examination of samples. No foreign body was found in the image so that cross - infection was impossible. 95 ot the 136 samples treated by raanual microscopic examination turned out to be negative while the rest were positive. However, according to, the ex-amination by the conventional analyzer of feces, 95 of the samples were normal, 13 had e rythrocytes, 25 had leukCK：ytes, 2 had yeast - like fungus, and 9 had lipid droplets. Conclusion The result of instrumental examination is as accurate as that of the conventional microscopic ex-amination when the same section of the sample is examined. However, the conventional anal.wzer of feces is user-friendly, standardized in the process of examining the ~mple, unlikely to make human induced errors and able to prevent cross - infection. This method is worthy of clinical application.
