目的：分析UF-1000i检测尿管型的准确性以及影响因素。方法①同一患者标本，UF-1000i检测尿管型与显微镜镜检管型阳性率比较；②分析 UF-1000i检测尿管型假阳性标本中，干扰因素所占百分比。结果①UF-1000i检测管型阳性率高于显微镜镜检，P<0.05；②影响假阳性干扰因素为粘丝线、纤维、上皮细胞、脓白细胞；结论尿沉渣分析仪检测管型的灵敏度和特异性都欠佳，同时存在假阳性与假阴性现象，只能作为管型检测的筛选。“,”Objective Analysis of UF-1000i urine tube and influencing factors. Methods ①The same patient specimens, UF-1000i-tube and microscope microscopic examination of urine-tube positive rate comparison UF-1000i; ②Analysis in tube type of false-positive urine specimens, interference factor percentage. Results ①UF-1000i test tube-positive rates than microscopes and microscopy, P<0.05; ②Factors af ecting false positive interference for the sticky threads, fibers, white cells epithelial cells, pus. Conclusion Urine detector tubes are poor sensitivity and specificity, both false positive and false negative phenomenon, only as a tube-type detection filter.
