尿液分析联合检测的应用价值

目的　探讨 U F- 1 0 0尿沉渣分析与干化学分析、显微镜检查联合检测尿液的应用价值。方法　用 U F-1 0 0型尿沉渣分析仪、尿自动分析装置 US- 2 1 0 0 R、常规尿沉渣镜检分别对 5 30例随机尿液标本进行检测。结果　以镜检结果为标准 ,U F- 1 0 0与常规镜检相比 ,检测红细胞阳性符合率为 89% ,假阳性为 1 5 .1 2 % ,假阴性率为 1 1 % ;测定白细胞阳性符合率为 92 .31 % ,假阳性率为 8.2 3% ,假阴性率为 7.6 9% ;检测上皮细胞、小园上皮细胞、管型、结晶和类酵母菌阳性符合率较低 ,分别为 80 .6 %、5 0 %、6 6 .7%、6 8.89%、5 7.1 2 %。 5 30例尿标本中干化学法白细胞、红细胞、蛋白及亚硝酸盐均阴性的 2 6 7例标本中 ,UF- 1 0 0检测红细胞阳性 2 2例 ,白细胞阳性 2 5例 ,常规检查法检出红细胞阳性 7例 ,白细胞阳性 1 9例。干化学法与镜检法相比 ,测定红细胞阳性符合率为 93% ,假阳性为 1 5 .1 2 % ,假阴性为 7% ;测定白细胞阳性符合率为 5 0 .4 3% ,假阳性为 3.1 1 % ,假阴性为 4 9.5 7%。结论　 UF- 1 0 0型尿沉渣分析仪与干化学分析、显微镜检查联合应用能弥补干化学法不足 ,减少漏检和误检 ,UF- 1 0 0尿沉渣分析仪还可以满足尿液检测标准化 ,而且通过对干化学与 U F- 1 0 0结果进行交叉核对会大大降

The applied value of combined urinalysis

Objective To investigate the value of UF 100 flow cytometer,dipstick test and microscopic observation.Methods 530 random samples were tested respectively by using UF 100 flow cytometer,dipstick fest and microscopic observation.Results Compared with microscopic sediment data,the positive corresponding rate,false positive rate and false negative rate in UF 100 test for RBC were 89%,15.12% and 11% respectively,and for WBC,92.31%,8.23% and 7.69% respectively.The positive corresponding rate for EC,SRC,CAST,X'TAL and YLC were 80.6%,50%,66.7%,68.89% and 57.12% respectively.In 530 urine samples,267 samples of RBC,WBC,protein and nitrite were all negative for dipstick test,among which UF 100 detected 22 samples RBC positive and 25 samples WBC positive,while manual microscopy detected 7 samples RBC positive and 19 samples WBC positive.Compared with microscopic sediment data the positive corresponding rate,false positive rate and false negative rate in dipstick test for RBC were 93%,15.2% and 7% and for WBC,50.43%,3.11% and 49.57%.Conclusion Joint application of UF 100 flow cytometer,dipstick test and manual microscopy could compensate each others inadequacy and satisty the standardization of urinalysis.Morever cross checking the results of UF 100 and dipstick test could greatly reduce the labor intension and improve the effectiveness.
