Albumin, Peritoneal Fluid
Also known as: Albumin, Abdominal Fluid, Albumin, Body Fluid, Albumin
Use
Peritoneal (ascites) fluid albumin measurement is used clinically to calculate the serum‑ascites albumin gradient (SAAG). SAAG values of 1.1 g/dL or higher suggest portal hypertension and assist in differentiating transudative vs exudative ascites. This aids in the diagnostic evaluation of ascites in patients with cirrhosis, malignancy, cardiac failure, or other causes of fluid accumulation ([mayocliniclabs.com](https://www.mayocliniclabs.com/test-catalog/overview/60622?utm_source=openai)).
