  Ehrlich醛反应法:可用于尿胆原定性和定量。试带灵敏度:Ames试带2mg/L,URITEST试带1-2mg/L,COMBUR-TEST试带4mg/L,偶氮法试带4mg/L。

  标本采集:一般留取中间段的尿液标本(即中段尿)。留尿方式可分为晨尿(包括首次晨尿和二次晨尿)和随机尿两种。标本的采集取决于临床医师的送检目的、病人的状况和试验要求。理想情况下,为了达到筛查、检出分析物和有意义的有形成分的目的,应收集浓缩尿液。一般要求住院病人留取首次晨尿;门诊、急诊患者可留取晨尿或随机尿。尿量:10~15 ml,约留样杯(50ml)半杯左右。尿标本须洁净,应避免异物的混入。男性一般要求避免精液、前列腺液的污染(特殊情况除外),女性最好冲洗外阴后再留取中段尿。如医生有特殊要求,可按医嘱留取标本。\\
标本采集:1.尿胆原测定应留取随机尿或定时新鲜尿标本。2.为了防止尿胆原氧化,最好使用棕色标本瓶。3.尿胆原在尿液酸性时排出减少,如事先让患者服用碳酸氢钠,可使尿液碱化,并收集下午2~4时内的尿液则可提高尿胆原的阳性检出。\\

  标本的运送:尿液留样杯上需粘贴患者标识号,该标识号可以是条形码,也可以是申请单的联号。如果是条形码应包含患者姓名、检验目的、标本类型、标本采集日期等信息。\\
标本运送:
收集好标本后应立即避光送检,为了防止尿胆原氧化丢失,如不能及时检测则必须冷冻保存。冰冻情况下尿胆原可稳定1个月,而冷藏18小时尿胆原下降60%。\\
