血尿素（Urea）的决定水平
参考值 3.6～7.1mmol/L 决定水平 临床意义及措施 3.0mmol/L 低于此值常见于血液释放过多或肝功能不全 7.1mmol/L 此值为正常上限，高于此值应考虑能引起尿素升高的多种可能原因，如肾功能不全、高蛋白饮食及上消化道出血等，此时测定血清肌酐有助于正确评价肾脏功能

血清尿素（UREA）测定的临床意义
升高：大致可分为三个阶段。浓度在8.2-17.9mmol/L时，常见于UREA产生过剩（如高蛋白饮食、糖尿病、重症肝病、高热等），或UREA排泻障碍（如轻度肾功能低下、高血压、痛风、多发性骨髓瘤、尿路闭塞、术后乏尿等）。浓度在17.9-35.7mmol/L时，常见于尿毒症前期、肝硬化、膀胱肿瘤等
