Albumin is mainly synthesized by the liver and represents approximately 50% of plasma proteins. Albumin’s primary function is the maintenance of oncotic pressure and the transport of a large number of compounds. The measurement of serum or plasma albumin is mostly indicated to help in diagnosing and monitoring diseases with protein loss or decreased synthesis (nephrotic syndrome, gastrointestinal loss, and hepatic insufficiency), acute and chronic inflammation, and severe malnutrition.
