Which lab value indicates nutritional status?

Which lab value indicates nutritional status?

• A. Albumin
• B. Hemoglobin
• C. Glucose
• D. Sodium

Answer: (A)

Albumin reflects visceral protein stores and overall nutritional status. It is a protein synthesized by the liver, and its levels tend to decrease with protein-energy malnutrition, making it a useful indicator of chronic nutritional status over time. Although albumin can be influenced by inflammation, liver function, and fluid status, among the options given it best represents nutrition-related protein reserves. Hemoglobin indicates anemia and oxygen-carrying capacity, not nutrition per se. Glucose shows carbohydrate metabolism and glycemic control, not nutritional stores. Sodium reflects hydration and electrolyte balance, not nutritional status. Therefore, albumin is the most appropriate marker for nutritional status among these values.
