24h尿蛋白定量,标本如何留取?关键4点要注意!

2016-12-18 佚名 检验医学网

这里给您介绍一个尿蛋白测定的“金标准”---24小时尿蛋白定量。它能很好的辅助肾脏疾病的诊断、疗效观察和预后判断。而影响这项结果至关重要的是尿液标本的正确收集、留取、保存和尿量的准确记录。首先,留取标本前3天避免大荤饮食和剧烈运动;女性患者应该避开生理期;如有尿路感染等情况也不宜留取尿液,因为此试验是计算尿蛋白的绝对值,与饮水量关系不大,所以,测定当天不必限制水分和进食量,如常进食便可以了。第二,

这里给您介绍一个尿蛋白测定的“金标准”---24小时尿蛋白定量。它能很好的辅助肾脏疾病的诊断、疗效观察和预后判断。而影响这项结果至关重要的是尿液标本的正确收集、留取、保存和尿量的准确记录。


首先,留取标本前3天避免大荤饮食和剧烈运动;女性患者应该避开生理期;如有尿路感染等情况也不宜留取尿液,因为此试验是计算尿蛋白的绝对值,与饮水量关系不大,所以,测定当天不必限制水分和进食量,如常进食便可以了。


第二,为准确测得24小时尿蛋白定量,早上8时应把膀胱内的尿排清并弃去,开始计时,每次排尿后可以把尿液通过漏斗转移到2升装的大饮料瓶子里,确保装进去前一定要把饮料瓶洗净,因为果汁里本来就有蛋白,避免干扰检查结果。然后盖上盖子就可以了。


第三,从计时开始到第二天早上8点止,把24小时所排出的尿全部贮存在一容器内,用量杯量总尿量,记录下来,然后搅拌均匀,取出一小杯放入专门的尿试管中送检。通过测定每100毫升的蛋白量,再根据实际总尿量进行计算,可得出24小时的蛋白量。


第四,遇气温高时(超过20度)可放冰箱保存或甲苯防腐,甲苯可在尿液表面形成薄膜,防止细菌繁殖,用量1.0-2.0ml甲苯/100ml尿液。


总之,要准确测得24小时尿蛋白量,必须准确收集24小时的总尿量,检测的部分是总尿量的混合液,才能保证检验结果的可靠性,为临床提供依据。
