Which laboratory value is commonly used as a nutritional indicator for wound healing potential?

• A. Hemoglobin 12-16 g/dL
• B. Albumin 3.5-5.0 g/dL
• C. Sodium level
• D. Platelet count

Answer: (B)

Maintenance of adequate protein stores is essential for wound healing because proteins supply amino acids for collagen synthesis, immune defense, and tissue repair. Albumin is a widely used nutritional indicator because it reflects systemic protein status. In the normal range of 3.5–5.0 g/dL, albumin suggests sufficient protein stores to support healing. When levels fall below this range, it signals protein depletion and a higher risk for delayed wound healing, edema, and infection. Keep in mind albumin can be influenced by inflammation, liver disease, hydration, and fluid shifts, so it’s best interpreted alongside clinical assessment and other markers. The other values describe aspects not directly tied to nutrition: hemoglobin indicates oxygen-carrying capacity; sodium is a salt balance measure; platelet count relates to clotting and inflammation. Therefore, albumin stands out as the most clinically relevant indicator of nutritional status related to wound healing potential.
