Assessing nutritional status, especially in monitoring the response to nutritional support in the acutely ill patient
Prealbumin is synthesized in the liver and acts as a binding protein for thyroxine and retinol-binding protein.
The serum concentration of prealbumin reflects the synthesis capacity of the liver and is markedly diminished in malnutrition and other conditions.
Due to its short half-life of approximately 2 days, prealbumin can be used for monitoring the nutritional status and efficacy of parenteral nutrition.
Values of 0 to 5 mg/dL, 5 to 10 mg/dL, and 10 to 15 mg/dL indicate severe, moderate, and mild protein depletion.
