Prealbumin (thyroxin-binding prealbumin) transports thyroid hormones thyroxin (T4) and triodothyronine (T3). It also transports vitamin A in association with retinol-binding globulin. Prealbumin levels are useful in the evaluation of several clinical conditions. Levels are decreased in most forms of acute and chronic hepatic disease. Prealbumin is a negative acute phase reactant with decreased levels associated with diseases involving inflammation or tissue necrosis.

Prealbumin has a circulation life of less than 2 days and is therefore a sensitive indicator of protein-calorie malnutrition.
