SerumAlbuminGradient
Serum Albumin Gradient (SAG) is a diagnostic tool used in the evaluation of liver disease, particularly in the context of cirrhosis. It involves measuring the albumin concentration in the blood serum at different levels, typically at the top, middle, and bottom of the serum column after centrifugation. The principle behind SAG is that in patients with cirrhosis, the albumin concentration decreases from the top to the bottom of the serum column due to the presence of ascites, a condition characterized by the accumulation of fluid in the abdominal cavity. This gradient is absent or minimal in patients without cirrhosis.
The SAG test is performed by drawing a blood sample and allowing it to clot. The serum
SAG is considered a sensitive and specific test for the diagnosis of cirrhosis. It is particularly useful
In summary, Serum Albumin Gradient is a valuable diagnostic tool in the evaluation of liver disease, particularly
