IQ200尿沉渣分析仪在腹透液常规检验中的应用

Application of IQ200 urinary sediment analyzer on the routine examination about peritoneal dialysis

目的探讨IQ200全自动尿沉渣分析仪(IQ200仪)用于腹透液常规检验的可行性。方法收集本院住院肾病患者的腹透液标本128例,用IQ200仪及手工显微镜法计数白细胞(WBC)和红细胞(RBC),统计比较两种方法所测定结果的一致性。结果就计数结果来看,在整个IQ200的线性范围内,仪器检测结果与手工镜检法结果比较,差异无统计学意义(P>0.05);在粒子数量范围,仪器检测结果与手工镜检结果的相关系数(r2)≥0.6。结论 IQ200全自动尿沉渣分析仪在腹透液细胞计数中具有一定的可靠性,与手工镜检结果有较高的相关性和一致性。相对于手工镜检,IQ200仪器的精密度高、重复性好,有一定的优越性,可以适当运用于临床腹透液细胞计数检测,减少手工镜检的操作步骤。

Objective To investigate the application value of IQ200 urinary sediment analyzer in the cell count of peritoneal dial- ysis solution. Methods A total of 128 peritoneal dialysis solution samples were collected. IQ200 and FAST-READER SY9502 were used to count the red blood cells and white blood cells. The results of 2 methods were compared. Results In whole linearity range, the results of IQ200 automatic urine sediment analyzer and manual microscopy had no statistical differences （P〉0.05）. In range of the number of paticales,the relativity coefficient was over 0.6. Conclusion IQ200 urinary sediment analyzer has certain reliability to cell count in peritoneal fluid with microscope examination in range over the number of particles. Compare with manual microsco- py,IQ200 has many advantages,for instance：high precision and well iterancy. It could be appropriate applicated in the cell count a- bout peritoneal dialysis that decrease the manual work.
