Principle PEG-enhanced immunoturbidimetric method.
Interpretation Prealbumin (transthyretin) is produced by the liver and functions as a minor carrier of thyroxine, transporting about one third of the active thyroid hormone. It is a stable glycoprotein with a short half life (two days) which makes it a sensitive indicator of any changes affecting prealbumin synthesis and catabolism. Prealbumin serum levels are generally decreased in protein-calorie malnutrition, various hepatobiliary diseases and acute inflammation. Its usefulness in measurement has been established as an indicator of nutritional requirements and response to therapy during total parenteral nutrition and to the nutritional adequacy of premature infants.
