Clinical Significance
Serum albumin measurements are used in the monitoring and treatment of numerous diseases involving primarily the liver and kidney. Its main value lies in the follow-up therapy where improvement in the serum albumin level is the best sign of successful medical treatment. There may also be a loss of albumin in the gastrointestinal tract, in the urine by the damaged kidney or direct loss of albumin through the skin. More than 50% of patients with gluten enteropathy have depressed albumin. The only cause of increased albumin is dehydration; there is no naturally occurring hyperalbuminemia.
