What is the reference range for prealbumin levels indicating adequate nutrition?

The reference range for prealbumin levels indicating adequate nutrition is 15-36 mg/dL. Prealbumin is a protein produced by the liver and is a good indicator of nutritional status because its levels can reflect short-term changes in protein intake and metabolism due to its relatively short half-life of about 2 to 3 days. Levels within the range of 15-36 mg/dL suggest that the individual is receiving adequate nutrition, while levels below this range may indicate malnutrition or nutritional deficiencies.

In contrast, the ranges specified in the other choices fall outside this optimal range, indicating potential nutritional inadequacies. Specifically, levels that are too low may suggest a lack of sufficient protein intake or other underlying health issues affecting nutritional status. Understanding these reference ranges is crucial for healthcare professionals when assessing a patient's nutritional status and planning appropriate interventions.
