Abstract
Objective To analyze and evaluate the results of urine red blood cells(RBC),white blood cells (WBC),casts and crystals(X'TAL)examined by two automated urine sediment quantitative analyzer(AVE-763B and UF1000i)and microscopic observation.Methods Urine samples of 150 patients were collected randomly and examined by using AVE-763B and UF-1000i for RBC,WBC,casts and crystals(X'TAL)at the same time.The results were compared with those of manual microscopy.Results Compared with microscopic sediment data the coincidence rate of AVE-763B for RBC was 91.33％,for WBC was 89.33％,for casts was 95.33％,for crystals(X'TAL)was 96.00％.The sensitivity of AVE763B for RBC was 80.95％,for WBC was 92.31％,for casts was 75.00％,for crystals(X'TAL)was 83.33％.The specificity of AVE-763B for RBC was 95.37％,for WBC was 87.06％,for casts was 96.48％,for crystals(X'TAL)was 96.52％.Compared with microscopic sediment data the coincidence rate of UF-1000i for RBC was 95.33％,for WBC was 91.30％,for casts was 92.67％,for crystals(X'TAL)was 98.00％.The sensitivity of UF-1000ifor RBC was 97.62％,for WBC was 90.77％,for casts was 87.50％,for crystals(X'TAL)was 83.33％.The specificity of UF-1000i for RBC was 94.44％,for WBC was 91.76％,for casts was 92.96％,for crystals(X'TAL)was 98.61％.The rate of carrying contamination in AVE-763B for RBC was 0.03％,for WBC was 0.08％,The rate of carrying contamination in UF-1000i for RBC was 0.75％,for WBC was 0.16％.There was no significant difference between UF1000i and AVE-763B.Conclusion All these two automated urine sediment quantitative analyzer have high sensitivity rate and low carryover rate iin detecting RBC,WBC,casts and crystals(X'TAL).It can be used for the screening of clinical specimens.It should be combined with microscopic observation in order to improve the checkout quality and assure the checkout accuracy.关键词
