Clinical Significance
Of all serum proteins, albumin is present in the highest concentration. It maintains the plasma oncotic pressure and the transport of many substances. Increased serum albumin may indicate dehydration or hyperinfusion with albumin; a decrease is found in rapid hydration, overhydration, severe malnutrition and malabsorption, severe diffuse liver necrosis, chronic active hepatitis, and neoplasia. Albumin is commonly reduced in chronic alcoholism, pregnancy, renal protein loss, thyroid dysfunction, peptic ulcer disease, and chronic inflammatory diseases.
