Comparison analysis on automatic urine sediment analyzer and microscope examination

Objective To analyze the detection capacity of visible component in urine by Sysmex UF-100 automatic urine sediment analyzer（UF-100 analyzer）.Methods The urine specimens were collected from 650 patients randomly,and were analyzed by UF-100 analyzer and microscope examination.Results Compared the results of UF-100 analyzer with microscope examination,the positive and negative coincidence rates and false positive and negative rates for red blood cell were 87.3%,85.7%,14.3% and 12.7%,for white blood cell were 90.2%,93.2%,6.8% and 9.8%,for crystal were 67.8%,93.1%,6.9% and 32.2%,for epithelial cell were 79.4%,85.2%,14.8% and 20.6%,for pipe model were 65.3%,92.2%,7.8% and 34.7%,and for yeast-like were 55.9%,91.7%,8.3% and 44.1%.Conclusions For the determination of components in urine,UF-100 analyzer is rapid and simple,but there are many effecting factors.When the crystal,yeast-like and pipe model are detected by UF-100 analyzer,for the kidney disease samples,the results should be checked by microscope examination.UF-100 analyzer can be applied for preliminary screening,but it can′t replace the microscope examination.
