摘　　要：血清腹水白蛋白梯度(serum ascites albumin gradient,SAAG)是血清白蛋白与同日内测得的腹水白蛋白之间的差值,是间接反映门静脉压力的指标。以SAAG≥11 g/L和SAAG<11 g/L将腹水分为门脉高压性和非门脉高压性,可用于腹水的病因诊断。近年来研究表明,SAAG在预测食管静脉曲张和肝性脑病的严重程度方面有一定的价值。Serum ascites albumin gradient （SAAG） was defined as the difference between serum ascites albumin and ascetic fluid albumin on the same day. It is an indirect parameter which reflected the portal vein pressure. SAAG≥ 11 g/L and SAAG 〈 11 g/L were used to distinguish portal-hypertension-related ascites and non-portal-hypertension-related ascites. Studies in recent years show that SAAG is valuable in predicting the degree of esophageal varices and hepatic encephalopathy.
