What is the expected reference range for prealbumin levels in a healthy adult?

The expected reference range for prealbumin levels in a healthy adult is typically between 15-36 mg/dL. Prealbumin, also known as transthyretin, is a protein produced by the liver that is used as a marker for nutritional status and for assessing protein synthesis. It has a shorter half-life compared to other proteins, which makes it responsive to changes in nutritional intake and inflammatory states.

Monitoring prealbumin levels is particularly useful in clinical settings for evaluating protein-energy malnutrition. Levels below the normal range may suggest malnutrition or hepatic dysfunction, while levels within or above the reference range indicate adequate protein intake and nutritional status. Hence, understanding this normal range is crucial for patient assessment in medical-surgical nursing.
