Clinical Info
Body Fluid Albumin may be used in classifying ascitic fluid into high-gradient or low-gradient fluids as determined by the serum-ascites albumin gradient, which is calculated as (serum albumin) – (ascites albumin). The serum and fluid specimens should be drawn with a minimal intervening time interval to appropriately analyze the gradient. Gradients = 1.1 g/dL are considered high, which reflects a high hydrostatic pressure, commonly caused by: cirrhosis or other processes generating portal hypertension. In samples where gradients are < 1.1 g/dL, ascites generated from conditions without portal hypertension should be considered. References: 1. CLSI.
