The Serum Ascites Albumin Gradient (SAAG) defines presence of portal hypertension (does not differentiate cause) in patients with ascites.

The serum-ascites albumin gradient or gap (SAAG) is a calculation used in medicine to help determine the cause of ascites. [1] The SAAG may be a better discriminant than the older method of classifying ascites fluid as a transudate versus exudate .

2018年7月2日 · The serum ascitic albumin gradient (SAAG) indirectly measures portal pressure and can be used to determine if ascites is due to portal hypertension. A high SAAG (>11 g/L) suggests the ascitic fluid is a transudate. A low SAAG (<11 g/L) suggests the ascitic fluid is …

The serum ascites albumin gradient (SAAG) is a formula used to assist in determining the etiology of ascites. Also see Medscape’s Ascites Albumin Gradient Calculator. The formula is below. SAAG =...

1.SAAG （serum albumin ascites gradient，血清腹水白蛋白梯度）是指血清白蛋白与同日内测得的腹水白蛋白之间的差值，即SAAG=血清白蛋白-腹水白蛋白。 由Hoefs于1978年提出。

The SAAG value, obtained through the ratio of serum to ascites albumin, provides valuable insights into the underlying cause of ascites. By analyzing SAAG values, healthcare professionals can determine the presence of portal hypertension …

It has been shown that SAAG is a better discriminator of portal hypertension than ascites. Patients with SAAG ≥ 1.1 gm/dL is considered as having high SAAG, indicating the presence of portal hypertension, while those with SAAG < 1.1 gm/dL are considered as having low SAAG, indicating the absence of portal hypertension.

2025年2月14日 · The serum–ascites albumin gradient (SAAG) is the difference between the concurrently obtained serum albumin concentration and the albumin concentration of the ascitic fluid obtained during paracentesis.

SAAG可用于判别腹水的病因，判定是否存在门脉高压：SAAG≥11g/L，提示患者有97%的可能患有门脉高压；SAAG＜11g/L，提示患者不存在门脉高压。 Runyon BA et al. The serum-ascites albumin gradient is superior to the exudate-transudate concept in the differential diagnosis of ascites. Ann Intern Med.1992;117 (3):215-20. Qx calculator. PubMed Link: http://www.QxMD.com/PubMed/1616215.

The serum-ascites albumin gradient (SAAG) is the most important diagnostic parameter in determining the cause of ascites. A SAAG of ≥ 1.1 g/dL indicates ascites from portal hypertension with a specificity of 97%. Ascitic fluid cell count, differential, and …
