An evaluation of cytology preparations made by the slide centrifuge and membrane filter techniques was made on 100 consecutive urine specimens from 46 patients. The membrane filter technique gave better cellular recovery and produced slides qualitatively superior to those prepared by the slide centrifuge technique. The former, therefore, is the recommended method. The slide centrifuge might be of greater value with urine of low cellularity where the membrane filter has provided only a few to practically no cells. The diagnostic accuracy on clinical follow-up of the patients included in this study is 94% for both methods, with no false positive cases and a 6% false negative rate. This high degree of accuracy indicates that these concentrating methods may lead to clinically valuable information if used routinely in the cytology laboratory.
对46例患者连续100份尿液标本采用玻片离心法和膜滤法制作的细胞学标本进行了评估。膜滤法能更好地回收细胞,制作出的玻片在质量上优于玻片离心法制作的玻片。因此,前者是推荐的方法。在细胞含量低的尿液中,膜滤法仅得到少量细胞甚至几乎没有细胞时,玻片离心法可能更有价值。本研究中患者临床随访的诊断准确率,两种方法均为94%,无假阳性病例,假阴性率为6%。这种高度的准确性表明,如果在细胞学实验室常规使用这些浓缩方法,可能会获得具有临床价值的信息。
