1.灵敏度和特异性\\
  尿色和尿透明度受尿液分析仪设计标准或观察者的主观因素的影响,尿液透明度还易受盐类结晶的影响。故尿液外观表示很难统一,临床应用中仅作为参考。\\
2.干扰因素 \\
  (1)防止污染:采用无色、沾净且无化学物质污染的容器采集尿液,收集尿标本前3d需禁服溴化物、碘化物等药物,以防出现假阳性反应。\\)
  (2)标本需新鲜:新鲜尿标本有助于准确判断尿色和透明度。尿放置时间过长盐类结晶析出、尿素分解产氨、尿胆原转为尿胆素、细菌增殖和腐败等多种因素均可使尿色加深、浑浊度增高。\\

  一般无特殊要求,最好处于安静状态,避免剧烈运动。\\

%%tab-标本采集和运送要求
  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。\\
