温度与时间对尿液分析仪检测潜血与血尿测定的影响

摘要
目的探究温度与时间对尿液分析仪检测潜血与血尿测定的影响,为提高检测的准确率寻求指导依据。方法选取2016年3月~2017年3月我院门诊就诊患者留取血尿标本为研究对象,在不同室温下放置不同的时间后,用尿液分析仪和显微镜下红细胞计数,比较各组间隐血测试情况和红细胞的减少情况。结果各组间隐血测试无改变,而镜检红细胞数随时间、温度的改变逐渐减少。相同来源的样品在12~22℃条件下检测结果优于22~30℃,差异有统计学意义(P<0.05)。结论尿液标本在12~22℃室温条件下保存时建议在2 h内完成检测,若室外温度较高时,应当在1 h内完成检测。
Objective To explore the influence of temperature and time on urine occult blood and hematuria determination by urine analyzer,so as to provide guidance for improving the accuracy of detection.Methods The hematuria was selected as the study object in the outpatient department of our hospital in March 2016 ~March 2017.After different room temperature at different room temperature,the urine analyzer and the erythrocyte count under microscope were used to compare the occult blood test and the reduction of red blood cells in each group.Results There was no change in the occult blood test among the groups,but the number of microscopic red blood cells changed gradually with time and temperature.The samples from the same source were better than 22~30 ℃ at 12~22℃,and the difference was statistically significant(P<0.05).Conclusion When urine specimens are stored at room temperature 12~22℃,it is recommended to complete the test within 2 h.If the outdoor temperature is high,the test should be completed within 1 h.
