ascites (serum - ascites albumin gradient >= 1.1 g/DL)
Last edited 06/2020
The serum-ascites albumin gradient is calculated via substracting the concentration of the ascites fluid albumin from serum albumin.- a serum-ascites albumin gradient of more than or equal to 1.1 g/dL predicts
portal hypertension with greater accuracy than the transudate/exudate classification
- causes of a high serum-ascites
albumin gradient include:
- Cirrhosis
- Congestive heart failure
- Fulminant hepatic failure
- Alcoholic hepatitis
- Liver metastases
- Veno-occlusive disease
- Portal vein thrombosis
- Budd?Chiari syndrome
- causes of a high serum-ascites
albumin gradient include:
