Clinical Significance
Measurements of albumin are used in the diagnosis and treatment of numerous diseases involving primarily the liver or kidneys. Decreased serum albumin concentration can result from liver disease. It can also result from kidney disease, which allows albumin to escape into the urine. Decreased serum albumin can also be explained by malnutrition or a low protein diet.
