%%tab-临床意义
尿色和透明度随机体生理或病理因素发生变化:\\
1.生理性变化\\
  某此代谢产物.如尿色素、尿胆原、尿胆素及尿卟啉等和食物、饮水及尿量的变化影响尿色;药物对球色也有影响:盐类结晶及酸碱度等的变化改变尿液浑浊程度。\\
__药物对尿色的影响__\\
||药物||尿色
|乙醇|苍白色
|大黄蒽醌|暗红色(碱性)、黄褐色(酸性)
|苯酚磺酸酞|粉红(碱性)
|氮唑沙宗、去铁胺、酚酞|红色、紫色
|核黄素、呋喃唑酮、小檗碱、牛黄、阿的平、吖啶黄|黄色、深黄色
|靛青红、亚甲蓝|蓝色
|山梨醇铁、苯、酚、利福平|棕色
|左旋多巴、激肽、灭滴灵、氯奎等|暗褐色、黑色
|番泻叶、山道年、非尼汀、苯茚满二酮等|橙色、橙黄色
|酚红、番泻叶、芦荟、氨基匹林、磺胺药等|红色、红褐色
|氨基甲酸酯|绿棕色
\\
2.病理性变化\\
尿色与浑浊度的病理性改变,因疾病不同表现各异。\\
__尿色异常及临床意义__\\
||尿色||临床意义
|无色/浅淡色|多尿、糖尿病、尿崩症
|深黄色|发热脱水
|浓茶色|肝细胞性黄疸、阻塞性黄疸
|红色|出血性疾病、月经血污染
|红褐色|溶血、肌损伤
|紫红色|卟啉病、临床有用药史
|棕黑色|标本放置过久、黑色素瘤(罕见)、药物史
|黄白色|泌尿系统感染
|绿蓝色|胆道疾病
|乳白色|丝虫病、淋巴管破裂
__尿浑浊及临床意义__\\
||浑浊状态||原因||临床意义
|云雾状|磷酸盐、碳酸盐结晶|可能有尿结石
| | 尿酸盐结晶|可能有尿结石
| | 草酸盐结晶|可能有尿结石
| | 红细胞|血尿
| | 白细胞、脓细胞|尿路感染
| | 细菌、真菌、精液、前列腺液|
|膜状|蛋白质、血细胞、上皮细胞|肾综合征出血热
|絮状|脓尿、组织、凝块、黏液丝、黏蛋白等|细菌感染
|乳状浑浊|乳糜尿、脂肪尿|丝虫病、淋巴管破裂、肾病

2.干扰因素 \\
  2.1.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。\\
  2.2.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。\\
